  ProCadd Look and Feel
  The layout of the ProCadd screen is highlighted by a large drawing
  "Window" on an unlimited drawing area.
  To the right or left, as your install parameters file determines,
  there is a menu section.
  At the initial or main menu there are thirty menu functions
  represented by a brief describing word or phrase.  These main
  functions can be invoked by pointing and clicking or by function
  key.
  These functions are grouped in sets of four.  The first twelve are
  keyboard selected by "F1" through "F12" and the second twelve are
  selected by "Shift-F1" through "Shift F-12".  The next six are
  keyboard selected by "Ctrl-F1" through "Ctrl-F6".
  After selecting the appropriate function, a function subset is
  displayed in the menu section.
  The entered main function being displayed, and highlighted on the
  top, is followed by a set of appropriate sub functions which are in
  turn followed by sub function parameters which when asked for have
  an accenting asterisk before them.
  Beneath the sub function parameters are attributes which relate to
  the appearance of the elements of the drawing.
  And below these is a window status area which locates the window
  within the drawing as well as identifying the current scale.
  Finally, there are facilities options, which when invoked prompt
  appropriate system requests or assists.
  To return to the main menu,  click on the highlighted menu title or
  press "ESC".
  Below the drawing area is also a status bar which will notify the
  operator when ProCadd is working.
  Drawing and Drawing Area
  ProCadd uses a Real World Coordinate system enabling the user to
  draw it as it is or will be and not concern himself with scaling to
  fit and since ProCadd provides an unlimited amount of space for
  your work you may use as much or as little as you choose anywhere
  within the drawing area.
  The size of the drawing that you are creating has no effect on the
  portion of the drawing that you are currently viewing.
  When in a one to one magnification mode, the screen representation
  is actually real size.
  Since ProCadd's drawing area is unlimited, for drawing composition
  purposes, there is no need for scaling.  ProCadd simply zooms in or
  falls back on the drawing as required.
  The portion that is being viewed is a window on the drawing.  The
  WINDOW may be positioned anywhere you choose.
  Zooming in on your drawing is the same as moving the WINDOW closer
  to the drawing or zooming in so that you will see less of the
  picture but a larger, more detailed image.
  Conversely scaling down shows a larger segment of the drawing but
  with smaller depictions.
  It is important to remember that the image on the screen is a
  representation of the drawing and not the actual drawing itself.
  It can never be as accurate as the plot.
  In order to increase the speed of updating the image that you see,
  some approximations are made in displaying certain elements.
  Circles may appear segmented, but when they plot, they will be the
  true circles that they represent.
  In addition, points may not always appear exactly positioned as
  they have been placed.  If a point is required at the intersection
  of two entities, the operator must first remember that each element
  is a separate entity and they only appear to connect.  When
  attempting to point and click on the intersection, ProCadd will
  either attach a position to one or the other element.  When the
  drawing is plotted the point may not be exactly at the desired
  position.
  In this case the "Intersect" position facility should be used so
  that ProCadd will understand that the intersection is desired.
  If properly coordinated using this and other later described
  locating methods, the points will print as required.
  Elements and Entities
  An element is a basic drawing unit.  Examples of elements may be
  line, circle, spline, etc.
  These basic units are the building blocks of a drawing.
  An entity is a set of elements that act as a single item.
  This Grouped entity is temporary.  If a permanent grouping is
  desired then the Combine function should be used.
  (See
COMBINE)
  The entity can be copied, moved rotated or deleted as a unit.
  The "GROUP" function will be discussed later as a drawing function.
  (See
GROUP)
  Displayable Attributes
  Displayable Attributes allow you to select the Color, Layer, Line
  Structure, and Width of the elements you are drawing.
  These attributes may be changed at any time that the menu section
  displays their status.  Once set, everything drawn will have the
  current attributes until changed again.
  (See
ATTRIBUTES)
  Active Drawing
  If you retrieve a drawing from the "Drawing Library" or create a
  new drawing, this drawing becomes the "Active Drawing" as displayed
  on the screen.
  The Active Drawing is worked with in a special utility section of
  ProCadd until it is time for storage at which a new name or
  revision will have to be assigned so that the original version can
  remain intact.
  ProCadd will not allow a drawing to overwrite an existing drawing
  in the "Drawing Library" without first warning the operator.  Then
  when the save is confirmed, ProCadd will take the original and
  rename the extension as XXXX.bak.  If there was previously a same
  named "bak" file, it then will be lost.
  Another invaluable feature of ProCadd automatically loads the
  Active Drawing upon entering ProCadd.
  When the system was exited last the current Active Drawing was
  saved in the utility files section of ProCadd and will remain as
  "Active" status until it is replaced with another drawing.
  Input Device
  An input device is quite simply the operator's method of
  communicating with ProCadd.
  The input devices available to the user are:
         1.  Keyboard
         2.  Mouse
         3.  Light Pen
  The input device can directly select a point in free space or
  establish a position on an existing entity or element.

Interpretation
  Position is established at any point on the drawing area by means
  of an Input Device or by using such an input device to allow
  ProCadd to select a precise location geometrically relative to some
  point, points, elements, or entities as identified by the operator.
  Cursor Movement

Movement
   > KEYBOARD  The four point arrow keys on the keyboard allow
     cursor movement in vertical or horizontal directions, vertical
     movement or Y axis movement by keying the up or down arrows
     and similarly horizontal movement along the right to left X
     axis through the right and left arrow keys.
     Unless otherwise specified pressing the right arrow key will
     move the cursor one unit of measure to the right which is
     also unless otherwise specified 1 inch as recognized by
     ProCadd.
     These units are either inches or centimeters depending on the
     user preference as is set in the Parameters File.  This variable
     is discussed in Appendix D of your manual.
     If the number key "2" is pressed prior to the arrow, the cursor
     will move 2 units in whichever direction specified relative to
     the previous location.  Likewise if we enter numerically 5.25
     then the right arrow key, the cursor will move 5 and 1/4
     inches toward the right from its previous location.  This
     location may be off the screen as you view it but it is a part
     of the now enlarged drawing area.
     Throughout ProCadd, distances, dimensions and coordinates can
     be listed in feet, feet/inch, decimal numeric or any
     combination thereof.  For instance, five feet and three and
     one half inches can be expressed in the following formats:
         1.  5' 3.5"                   5.  63.5"
         2.  5' 3.5                    6.  63.5
         3.  5' 3 1/2                  7.  63 1/2
         4.  5.25' 1/2"
     Notice that the second, third, sixth and seventh options have
     not been listed with inch specific notation.  This is because
     when in the U.S. type foot/inch format ProCadd's Real World
     Grid Coordinate system default to one inch spacing.
     Note that if the Metric option is specified in your parameters
     file as discussed in the parameters appendix, the default
     spacing will be one centimeter.  In this case, unqualified
     length entries will be interpreted as centimeters.  The user can
     however qualify the length by specifying mm, cm, dm, m or km.
     If your keyboard does not have arrow keys then a position
     relative to the current one can be attained by typing the
     distance and direction.  For instance typing ".2" followed by
     "D" and "X" sends the cursor 2 tenths of a unit to the right.
     Entering "-.2DX" sends the cursor to the left.  Numerical
     entry followed by "DY" similarly controls vertical movement.
     Note that a position need not be established on screen.
     ProCadd will act identically with regard to keyboard
     positioning and Real World Coordinates regardless of the
     current view location on the drawing area.
     Specific positioning can also be attained by entering "X" and
     "Y" coordinates.
     Entering coordinates 0-X,0-Y locates the cursor at the origin
     of the imaginary grid on the drawing area.
     (See
DRAWING/SET
ORIGIN)
     Similarly 1-X,1-Y will locate the cursor 1 unit above and 1
     unit to the right of the origin.
     Negative digit entry will locate points below or to the left
     of the Origin.
     Once any of these locations is achieved as desired a click of
     the enter key will establish that point for use.
   > MOUSE OR LIGHT PEN  Since a mouse will be most commonly used
     this writing we will refer to it instead of a light pen or
     other similar device.
     The mouse can locate points or identify entities by simply
     pointing and establishing the position with a click of the
     left button.
     The mouse would most commonly be used to pick a point on or
     existing entities as ProCadd will choose the closest point on
     the element or an endpoint if possible when the mouse is
     clicked near that element.
     Note: If a point is desired near to but not on a nearby
     entity, the cursor location can be held and established by
     first locating with mouse action and then establishing the
     point with the enter key on the keyboard.
     The mouse can position freely within the drawing as viewed but
     if a point off screen is desired and is to be located by
     mouse, then the window scale must be adjusted for a broader
     view or the screen can be panned to that location.

Utility
   The position facilities of ProCadd will, upon request, allow
   points to be defined based on certain useful rules of geometry
   as applied to existing entities.
   At the bottom of the drawing function menus there are subsets
   of facility options such as midpoint, circle center, and
   intersection.
   These facility options are accessed by either pointing the
   mouse and clicking on the desired tool or by striking the
   keyboard key representing the first letter of the option
   (i.e., the letter "m" selects "midpoint").
   Also included are logical position assistance features such as
   "last point" and grid overlays.
   In the following you will find descriptions of sequences
   required in identifying the elements properly so that ProCadd
   can establish the desired point.
   > LAST POINT - This option when selected prompts ProCadd to
     re-establish the point which was last defined.  If for
     instance, after constructing a line, you wish to begin
     another element by identifying it first by a point where the
     line left off, the selection of  "last point" will
     establish that point as the first step in construction of the
     new element.
   > GRID ON/OFF - The option "Grid" is a toggle on, toggle
     off feature.  When on, this option invokes a limited grid
     around the cursor in the form of patterned dots to assist the
     operator in locating points or assessing position.  These dots
     will follow the cursor about the drawing until the option is
     toggled off.
     The spacing option of the grid function will alter the spacing
     between the dots of the grid.  Pressing the letter "S" while
     the grid is toggled on or selecting it with the mouse will
     prompt a distance request for space between the dots.  If the
     exact distance is known then keying in a number followed by
     "enter" will specify the distance.  However, ProCadd can
     identify a distance through one of the other distance
     facilities at the bottom of the menu section.
     Selecting "line length" followed by the selection of an
     element of the drawing will establish grid sectioning
     equivalent to that length.  Similarly, "arc length" and
     "radius" will section the grid equal to those distances as
     specified.
     If the grid spacing distance measurement is entered naked
     without any qualifying unit of measure, it will be assumed
     that inches are intended  when in U.S. mode and in the case
     of metric mode, centimeters are understood.
     The "origin", or center of the grid follows the cursor around
     in a precise manner as determined by the spacing option
     setting and the position coordinates.  In other words, if the
     spacing option is set at one inch, the grid will follow the
     cursor around, jumping in one inch increments and aligned with
     the real X and Y coordinates as tracked by ProCadd.
     The grid can be centered to any point as desired by using the
     "origin" option.  Simply pressing the letter "O" followed by a
     new origin selected with an input device are all that is
     required to realign the grid as to pass through the new
     origin.
     The spacing is very important to the use of the grid option
     because when invoked, the only available points of attachment
     are on the grid points.  It works like a distance limiter with
     the defined distances being multiples of the grid spacing.
   > ALIGN - Selection of this item will establish a position
     based on the vertical and horizontal extension of specified X
     and Y coordinates.
          Procedure
          =========
       -> Step 1. Pick the menu item "align."
   POS -> Step 2. Then specify an X coordinate through which a real
          or imaginary vertical line will pass.
   POS -> Step 3. Then specify using an input device a Y coordinate
          through which the imaginary horizontal component will
          pass.
     A position point will then appear at the point of alignment.
   > CIRCLE CENTER - This menu item is used to precisely
     locate the center of circular elements such as arcs, ellipses,
     circles or an imaginary circle.*  When requiring this center
     use the following sequence:
          Procedure
          =========
       -> Step 1. Pick the menu item "CIR CEN" or press the letter
          "C."
   POS -> Step 2. Select the entity within which the center is to
          be located.
          Note:  Do not select an endpoint of an arc.
   POS -> Step 2* In the case of an imaginary circle, first the
          points are required through which an imaginary circle
          would pass.
          Identify these three with the first being other than a
          circular element.
   > MIDPOINT - This menu item positions a point midway on a
     line or between two points.*
          Procedure
          =========
       -> Step 1. Select "MIDPOINT" or the letter "M."
   POS -> Step 2. Select the line element from which a midpoint is
          to be established or both ends of the line.
          When ProCadd does not recognize the final point as an
          element, it will wait for the operator to select a second
          point.
   POS -> Step 2* Specify two points the first of which is other
          than on a line.
   > INTERSECT - The menu item "INTERSECT" will find the
     intersection of any two elements.  If more than one
     intersection is found, the intersection closest to the points
     selected will be used.
          Procedure
          =========
       -> Step 1. Select the "INTERSECT" menu item or "I."
   POS -> Step 2. Pick a point on the first element in the equation
          other than its endpoint.  If a point other than the
          endpoint is selected then a second point on that element
          is required in order to complete identification of that
          element.
   POS -> Step 3. Pick the second element similar to the way the
          first was selected in step 2.
     An exact intersection will be produced.
     Note that two points in free space can be selected and the
     vector of the an imaginary line between them will be used as
     either the first or the second element to which an
     intersection will be found.
   > DIRECTION AND DISTANCE - When selecting the menu item
     "DIR/DIST" you are allowed to identify a point which is a
     specific direction and distance relative to a known point of
     origin, or "LAST POINT."
          Procedure
          =========
       -> Step 1. Select the "DIR/DIST" menu item or press "D."  A
          small square will appear at the last defined point to
          indicate the origin of the function.
   DIR -> Step 2. Specify a direction using the direction
          facilities. Click on a point on the compass rose, specify
          a degree heading, or select an element of an angle to
          match.  A line will appear showing the direction.
   DIST-> Step 3. Specify a distance.
     This locates a point relative to the origin in a known
     direction and at a known distance.
   > PORTS - This item is a toggle on and toggle off menu
     item.  When ports are specified on a drawing, the ports
     are the only points which can be selected.  In order to
     deselect this port lock, the menu item "PORTS ON" should be
     selected and it will toggle to "PORTS OFF" notifying the
     operator of the new status.  Any point on the ported entity
     can now be selected. (See
PORTS)
   > HOLD - The "HOLD" menu item allows the operator to use a
     point without defining it as a step in some routine.  It helps
     when specifying points of origin such as the one required when
     using "DIR/DIST."  Select "HOLD" on the menu or "H" and follow
     with a point then this point becomes the last point and
     not a step in some routine to follow.
  Distance Facilities

         Geometric
Interpretation
  The term Distance Facilities describes the methods available to the
  ProCadd operator enabling him to specify lengths or distances as
  required.
  There are several ways to specify distance.
  If the exact distance is known then it can be numerically
  entered.
  The distance can be entered as an expression of feet,
  feet/inches, inches, millimeters, centimeters, decimeters,
  meters or kilometers.    See KEYBOARD for distance
  entry methods.
  Note that while in metric mode, qualified entry will be
  correctly understood by ProCadd.  In other word, when in U.S.
  standard mode, a naked entry of 1 is considered as 1 inch.
  A qualified entry if 1 cm while in U.S. mode would be considered
  1 centimeter as intended.
  At any time a Distance entry is required, the user may wish to
  indicate that distance as a relation to some area of the
  drawing.  The operator can therefore locate two points in
  succession on the drawing and ProCadd Cadd will use the
  distance between the points as the distance desired in the
  function where the request was made.

  the menu section when a distance request is made.
   > LINE LENGTH - Selecting "LINE LENGTH" or typing "L" on
     the keyboard to be followed by the selection of a linear
     element will interpret the distance request as the length of
     the element selected.
   > ARC LENGTH - Selecting the ARC LENGTH" or typing "A"
     followed by specifying a circular element will interpret the
     distance request as the circumference of the element.
   > RADIUS - Selecting "RADIUS" or "R" followed by
     referencing a circular element will specify the radius of the
     element as the distance entry.

Elements
  Direction Facilities are methods available to the ProCadd operator
  used to specify direction.
  Unless otherwise specified, as we will discuss, the angle
  represents a inclining slope beginning with 0 degrees which
  indicates a direction to the right as viewed.  Progressively
  increasing, the degree rotates the heading counter-clockwise.
  Similarly 90 degrees would be up and 270 degrees would be down.
  There are several Direction Facilities available to the user.
  These methods can be used in combination as well.  If for instance,
  if a direction is needed 90 degrees as related to an element, or
  perpendicular, the following sequence would apply.
  First type in 90, but do not press "enter." Then specify the
  element to which the new direction will be perpendicular, by
  entry of two points on the element.
  Upon the establishment of the second, a vector as requested will
  appear from the previous point.
  Numeric Entry
  If a direction is known, it can be typed in directly from the
  keyboard in either degrees, minutes, seconds; or decimal
  degrees.  After the angle value is input press the "enter" key
  to accept.
  Rose Selection
  Common values can be specified at 30, 45, 60 degree increments
  by clicking on the compass rose at the bottom of the menu
  section when a direction request is made.
  Freehand Direction
  Two points can be randomly specified and the direction from
  the first point to the second point as relative to zero
  degrees right will be used.
  Emulation of Existing Entities
  An existing element can also be used.  If an element is
  specified, then its direction will be used.  Remember that a
  vertical line may have been created in a 90 degree direction
  or a 270 degree direction.
  Metric Program Operation
  The standard base unit upon which the ProCadd program operates is
  an inch, however, the program will default to one centimeter if
  desired.
  In the Parameters File there is a parameter named "user_units=".
  This variable setting determines the default mode of operation and
  the format which the drawing files are stored.  Refer to Appendix D
  of your manual for parameter definitions and settings.
  When in metric mode, the unit of measure as moved on the drawing
  and used by the Distance Facilities is one centimeter.
  Similar to the way directional movement is conducted, the Real
  World Coordinate System is metric scaled.
  If distance entries are, however, defined as inches with "in" or
  tickmarks, these identifiers will override the current status mode
  of the program.
  Similarly, while in U.S. mode, entries identified with metric
  notations i.e. cm, mm, km, etc... will be recognized accordingly.
  This is very useful when environments require combined usage of
  both measurement standards in the same drawing.
  There are several areas of the program effected by metric
  operation.
  These include:
      Distance Facilities
      Dimension Functions
      Grid Option
      Fillet Drawing Function
      Circle Drawing Function
      Text Insert/Editing
      Plot/Print Function
      Window
      Ellipse Drawing Function
  In each of these portions of the manual, metric alternate operation
  will be mentioned.

               -> Break
Segments
  From the main function selection menu, the operator can request
  Line functions by either pointing and clicking on the menu item
  "LINE" or by pressing "F1".
  Following are a set of sub function parameters which limit the
  directions of the lines being created.  An asterisk toggled on upon
  selection invokes the limit.
  > ALL DIRECTIONS  When creating lines this parameter when
    selected allows the user to define lines in any direction.
  > FOUR DIRECTIONS  The Four Directions parameter limits
    the creation of lines to 0, 90, 180 and 270 degree directions.
  > EIGHT DIRECTIONS  The Eight Directions parameter limits
    creation of lines to 45 degree spaced directions beginning at
    zero degrees.
  > ISOMETRIC  The Isometric parameter option will limit
    directions to six different directions which help the operator
    when using perspective view angles to portray depth.  These
    angles are 30, 90, 150, 210, 270 and 330 degrees.
  > TANGENT TO  The Tangent To option when used directs the
    line being created to a point Tangent To a circle or arc.
    When defining the line, assign one end to a circle or an arc.
  Beneath the parameters are Displayable Attributes which determine
  the color, width, structure and layer of the element.
  (See
ATTRIBUTES)
  Also on the menu is the Window status area.  Note that at any time,
  the operator can go directly to the Window menu by clicking on the
  window outline and return by pressing "F1."
  (See WINDOW):window}
  Finally at the bottom of the menu section there are facility
  selections.
  Point,Point Defined
  This sub-function allows lines to be drawn by specifying two
  endpoints.  Position Facilities are used to define these
  points.
  Note that if the Four Directions parameter is selected, that
  the line can only be created in a vertical or horizontal
  direction.
  Likewise if the Eight Direction parameter is selected then
  only lines at 45 degree increments can be drawn.  The Tangent
  To option mandates that the line created will connect tangent
  to a circle or arc if one of the endpoints selected is located
  on the circle.
         Procedure
         =========
      -> Step 1.  Select the Point/Point menu item (unless already
         selected, this one is default)
  POS -> Step 2.  Locate the first point.
  POS -> Step 3.  Locate the second point and upon acceptance of the
         second point a line will be placed between them.  Note that
         while positioning the second point, an indicating ghost line
         will appear where the line would be to assist the operator in
         placement.
  Slope,Point Defined
  This sub-function allows the creation of a line at a given
  slope which will intersect a point as specified and extend the
  extent of the screen only.
  These lines are generally used as construction guidelines
  which are later either deleted or modified.
         Procedure
         =========
      -> Step 1.  Select the Slope/Point menu item (if not already
         selected from previous operation).
  DIR -> Step 2.  Specify a slope degree by clicking on the slope
         request and specifying a direction either by numeric entry or
         rose selection.
  POS -> Step 3.  Identify the point through which the line will
         travel.
         Note that a ghost line appears, to assist the operator in
         placement of the line.
  Chain Lines
  The Chain Line is identical to the Point/Point line except
  that the final point of each segment of the line serves
  immediately as the first point of the next extension of the
  Chain Line.
         Procedure
         =========
      -> Step 1. Select the Chain Line menu item.
  POS -> Step 2. Position the first point of the first segment of the
         Chain Line.
  POS -> Step 3. Position the second point of the segment.  A ghost
         line will guide you.  This point will serve as the first point
         of the following element.
  POS -> Step 4. Repeat Step 3 until the chain is complete.
  Modifying Lines
  The Modify sub-function changes both end points of a line
  without changing the slope or relative location of the line.
         Procedure
         =========
      -> Step 1. Select the Modify sub-function.
  POS -> Step 2. Specify the line element to be modified by selection
         of any point on the line.  This location on the element is not
         important.
  POS -> Step 3. Locate one new endpoint on the line selected.  The end
         of the existing line that is closest to this point will move
         to this point when the line is re drawn.
  POS -> Step 4. Select a new endpoint for the other end of the line.
         Upon this selection, the line will be re drawn.
  Modify One End
  The Modify One End sub-function allows for the modification of
  only one end of a line.
         Procedure
         =========
      -> Step 1.  Select the Modify One End sub-function.
  POS -> Step 2.  Select the line to be modified by locating a point on
         the element closer to the end to be modified than to the other
         end.
  POS -> Step 3.  Specify the new endpoint.  The line will be re drawn
         upon this selection.
  Trim Lines
  The Trim sub function allows the user to trim a line to a
  specific point or element.
         Procedure
         =========
      -> Step 1. Select the Trim sub function.
  POS -> Step 2. Select a point or an element to which the line will be
         trimmed to.
  POS -> Step 3. Select the line to be modified.  The end of the line
         toward which it's identifying point lies will be trimmed to
         the point as specified in Step 2.
  POS -> Step 4. If Step 2 is an element and multiple intersecting
         lines are to be trimmed then repeat Step 3 until all lines are
         trimmed.
  Break Lines
  The Break Line sub-function allows the operator to break a
  line into segments.
         Procedure
         =========
      -> Step 1.  Select the Break Line sub-function.
  POS -> Step 2.  Select the line element to be segmented by locating a
         point anywhere on the line.
  POS -> Step 3.  Select a point on the line where the break is to
         begin.
  POS -> Step 4.  Select a point on the line where the break is to end.
  It is important to note that even though the line has been
  broken into segments, it still will act as a single entity.
  If the operator wishes to separate the segments into separate
  elements then the Separate command must be used.

  the "F2" key.
  The Rectangle sub menu is made up of three Rectangle sub functions.
  Beneath the sub-function selection menu are the standard attributes
  selections, Window status area, and facilities selections.
  Point,Point Defined
  This Rectangle sub-function allows creation of rectangles when
  the operator supplies diagonally opposed corner points.
         Procedure
         =========
      -> Step 1. Select the Point/Point sub-function.
  POS -> Step 2. Locate the point designating the first corner of the
         rectangle.
  POS -> Step 3. A ghost rectangle will follow the cursor movements
         proposing the element's shape as you then proceed to locate
         the second corner.
  Once the second point is selected, the rectangle will be
  drawn.
  Center,Point Defined
  This Rectangle sub-function assists the operator in elementary
  creation of a rectangle by specifying a center point along
  with one corner.
         Procedure
         =========
      -> Step 1. Select the Center/Point sub-function.
  POS -> Step 2. Locate a center point position.
  POS -> Step 3. Locate the corner position.  Notice that as before,
         the ghost follows cursor movement until the final position
         is established, at which time, the permanent rectangle is
         drawn.
  Concentric Rectangles
  The Concentric sub-function allows for creation of multiple
  elements with the same center.
         Procedure
         =========
      -> Step 1. Select the Concentric sub-function.
  POS -> Step 2. Identify a point as the center.
  POS -> Step 3. Locate a corner point for the initial concentric
         rectangle.  Again a ghost element will follow.
  POS -> Step 4. Repeat step 3 by locating subsequent corner points
         until all concentric rectangles have been placed as desired.

  In order to make use of the Circle/Circle set of sub
  functions, click on the Circle option.  As asterisk will
  appear directly before the option indicating it's selected
  status.
  If while using one of the Circle/Circle sub functions, the
  Tangent To parameter is selected by clicking on it, the
  perimeter of the circle will be established based on the
  selection of a point on the element which the circle will be
  tangent to.
  Center,Point Defined
  This sub option is used to create circles by establishing a
  center point followed by a point through which the perimeter
  will intersect.
         Procedure
         =========
      -> Step 1. Select the Center/Point sub-function.
  POS -> Step 2. Locate a point to be used as the center of the circle.
  POS -> Step 3. Locate a perimeter point through which the circle will
         be drawn.
  Note that the ghost follows until the perimeter point is
  established in the form of a circle or a square depending on
  the main program parameter setup.
  Point,Center Defined
  This Point/Center sub-function operates similar to the
  previous Center/Point sub-function with the only difference
  being that the perimeter point is specified first and followed
  by the center point.
         Procedure
         =========
      -> Step 1. Select the Point/Center sub-function.
  POS -> Step 2. Locate the perimeter point as required.
  POS -> Step 3. Locate the center point as desired.
  Note that when the center is established and the circle is
  drawn, if the Tangent To parameter is selected and the
  perimeter point is located on another element, then the
  perimeter point and radius will be adjusted so that the circle
  is tangent to the element.
  Concentric Circles
  The Circle/Concentric sub-function is used for making multiple
  circular elements with the same center by locating multiple
  perimeter locations.
         Procedure
         =========
      -> Step 1. Select the Circle/Concentric sub-function.
  POS -> Step 2. Locate the center as desired for the concentric
         circles.
  POS -> Step 3. Establish a point for the desired perimeter upon which
         the circle will be drawn.
  POS -> Step 4. Locate a point for the second concentric circle and
         repeat as many times as are circles required.
  Three Point Defined
  This sub-function allows circles to be drawn by selecting
  three points on the perimeter of the proposed circle.
         Procedure
         =========
      -> Step 1. Select the Circle/3 Points sub-function.
  POS -> Step 2. Locate the first point on the perimeter of the circle
         you wish to draw.
  POS -> Step 3. Locate a second point on the perimeter of the circle
         you wish to draw.
  POS -> Step 4. Locate the final point on the perimeter of the circle
         you wish to draw and upon that entry, the circle will appear.
  If the three points are collinear, no point will be drawn.
  Radius,Point,Point Defined
  This sub function assists the operator in creating a circle by
  specifying a radial dimension followed by two points to be on
  the perimeter of the circle being drawn.
  Notice that upon selection of the Rad/Point/Point menu item
  that the standard position request facility subset of options
  at the bottom of the menu disappears and a set of three
  distance request facility options appears.
  This distance input is requested as the first portion of the
  element construction.
         Procedure
         =========
      -> Step 1. Select the Rad/Point/Point menu item.
  DIST-> Step 2. Specify a distance to be considered as the radius of
         the circle to be drawn.  You may numerically input a value or
         use one of the distance assists at the bottom of the menu
         selection.
  POS -> Step 3. Choose a point which will be the first perimeter point
         of the circle being drawn.
  POS -> Step 4. Locate the second perimeter point through which the
         circle will intersect.  Upon selection of this element the
         circle will appear.
  Note that if the distance between the perimeter points is
  greater than twice the radial measurement, no circle will
  be drawn.
  Tangent,Tangent Defined
  This Circle/Tangent/Tangent sub function assists the operator
  in the creation of circles while specifying tangency to two
  separate entities.
         Procedure
         =========
      -> Step 1. Select the Tangent/Tangent sub function.
  POS -> Step 2. Select the first element to which the circle to be
         drawn will be tangent to.  The Circle will be tangent to this
         element at this point.
  POS -> Step 3. Select the second element to which the circle will be
         tangent to.
         Upon the second selection, the circle will be drawn.
         Note that the circle's diameter will be determined by the
         location of the first point on the element to which the circle
         being drawn is tangent to.

Tangent
Defined
  The ARC set of sub functions enables the operator to draw arcs
  in a variety of ways.  There are three Arc sub functions that
  appear when the Arc option is selected.
  Keep in mind that arcs are always defined in a counter-
  clockwise direction.
  Three Point Defined
  The Arc/3 Points sub function creates arcs by specifying three
  points.  The arc will begin at the first point, end at the
  second point and pass through the third point.
         Procedure
         =========
      -> Step 1. Select the Arc/3 Points sub function.
  POS -> Step 2. Position a point to be the beginning of the desired
         arc.
  POS -> Step 3. Establish a point to be the end of the desired arc.
  POS -> Step 4. Select the final point on the circumference through
         which the arc will pass.
  Since the arc will always draw in a counter-clockwise
  direction, a first point positioned on the left followed by a
  second point on the right will indicate an arc downward.  On
  the other hand an arc defined by a first point on the right
  and followed by a second point on the left will draw an upward
  arc.
  Radius,Point,Point Defined
  The Arc/Rad/Point/Point sub function allows the user to define
  an arc by specifying a radius followed by a beginning point
  and then an ending point.
         Procedure
         =========
      -> Step 1: Select the Arc/Rad/Point/Point sub function.
  DIST-> Step 2: Enter a radial measurement using the keyboard or one
         of the distance tools that appear at the bottom of the menu
         section as the distance definition which is required.
  POS -> Step 3: Establish the point to be used as the starting point
         of the arc to be drawn.
  POS -> Step 4: Locate the ending point for the arc to be drawn.
  Upon selection of the final point, the arc will appear.
  Note that the order of which the two arc end points are
  entered is important.  The arc will begin at the first
  point and draw towards the second, radiating
  counter-clockwise until reaching the second.  The order of
  entry therefore determines to which side of the endpoints
  points the arc will lie.
  Tangent,Tangent Defined
  This Arc/Tangent/Tangent sub function will draw arcs as
  required tangent two separate entities.
  When selecting the Tangent/Tangent option of the Arc sub
  function, a clockwise/counter-clockwise toggling option
  appears.  For this Tangent/Tangent option the user can define
  the arc in a clockwise fashion if desired.
         Procedure
      -> Step 1. Select the Arc/Tangent/Tangent sub function.
  POS -> Step 2. Locate a starting point on an entity to which the arc
         will be tangent.
  POS -> Step 3. Locate the ending point on an entity to which the arc
         will be tangent.
  Upon establishment of the final point, an arc will be drawn.
  If tangency is not possible as defined, then no arc will be
  drawn.
  Modifying Circles and Arcs
  The Modify option within the Circle function is used to modify
  existing circles and arcs.  As was during their creation, the
  new endpoints must be specified on a counter-clockwise basis.
         Procedure
         =========
      -> Step 1. Select the Modify sub function.
  POS -> Step 2. Select the element to be modified.  The position of
         the selection point is irrelevant as long as it is not an
         endpoint.
  POS -> Step 3. Position a point to be the new beginning point of the
         circle or arc being modified.
  POS -> Step 4. Select a position point for the new ending point of
         the circle or arc being modified.
  After establishment of the final ending point the element will
  be re-drawn.

  The WINDOW features allow the operator to select the viewed portion
  of the drawing that is being worked on.
  Portions of the drawing can be zoomed in on and this enlarged
  portrait can pan across the full drawing as desired.
  The Window menu selection subset can be entered in three ways.
  First would be to click on the "WINDOW" feature of the main menu
  selection area.
  Window can also be entered by pressing "F4" at any point.
  Finally, if the operator is currently in one the drawing function
  menus he can click on the rectangular outline of the drawing area
  referred to as the Window View Locator in the window status section
  of the menu.  This will take the user directly to the Window menu.
  The Window sub function menu features two options being Set Size
  and Set Bounds.
  Beneath these on the menu is the Reload function.
  Beneath the Reload option are the Layer control functions.
  Following these Layer options are the Window View Locator and scale
  adjustments and finally below that is the facility request area.
  Set Window Size
  The Set Size sub function of the Window menu is used to adjust
  the viewed area of the drawing screen to view a specifically
  sized view of the drawing.
         Procedure
         =========
      -> Step 1. Select the Set Size sub function.
  DIST-> Step 2. Pick a distance by using one of the distance facility
         options at the bottom of the menu section and following with
         the selection of the appropriate element or just entering a
         value via the keyboard.
  Once a distance is specified, the screen will adjust to a
  magnification factor where the horizontal dimension of the
  viewed area is as requested.
  Set Window Boundaries
  The Set Bounds sub function of the Window menu is used to
  specify a window viewing boundary as desired.
         Procedure
         =========
      -> Step 1. Select the Set Bounds sub function.
  POS -> Step 2. Locate a point to be one diagonally positioned corner
         point for the new boundary as desired.
  POS -> Step 3. Locate a point to be the opposite corner of the new
         viewing screen boundary.
  Upon establishment of the final corner, the screen will be
  readjusted.  Notice that as the second point is being
  positioned a ghost sample of the result will follow.
  Reload Drawing
  The Reload option redraws the current drawing thereby
  including any changes.  If for instance, a Layer is toggled
  off, the elements included in that layer will not disappear
  until the drawing is reloaded.
  The Reload function is invoked by clicking on the word
  "RELOAD" at the Window menu or at any point in ProCadd by
  pressing "CTRL-R".
  Layer Controls
  This section of the menu controls the selection of Layers
  applicable to the current drawing.
  Layers can be used to assign viewing status to different parts
  of a drawing.  An operator may for instance draw the basic
  structure of a building on layer one.  The electrical schemes
  may be on layer two.  The plumbing could be on layer three.
  Perhaps the foundation plan would be on layer four.
  Descriptions, notes, or lists of materials might be on layer
  five.
  Generally users will develop their own standard set of layer
  designations.
  There are 120 layers available to be used or not used as
  desired.
  The first option of the Layer set of options is "ALL ON/OFF".
  Clicking on the "ON" portion of the phrase will turn all
  layers on.  Likewise clicking on the "OFF" portion of the
  phrase will conversely turn them all off.
  The next items "+10/-10" control the layers shown in the menu
  section.  Clicking on "+10" ascends the layer grouping by ten
  and likewise the "-10" descends the layer grouping.
  The listed group of ten layers can be selectively toggled on
  or off by clicking on the individual layer thereby toggling it
  to an active status.
  Note that when layer status is changed, it will not effect the
  view of the drawing until it is reloaded by clicking on the
  above "RELOAD" or pressing the combination "CTRL-R".
  Window View Locator
  The Window View Locator shows you the location and relative
  size of the view you are currently using relative to the
  entire drawing.  The locator is two rectangles, the outside
  rectangle shows the size of the full drawing while the inside
  rectangle shows the position of drawing that you are currently
  viewing.
  The current window scale is listed below the window view
  locator.
  If the full drawing is on screen the window view locator will
  appear as one rectangle.
  A list of scale changes are displayed around the window view
  locator.  These numbers represent a scaling factor that will
  be applied to the current status.  The values range from "8"
  (an 8x zoom in) to "1/8" (an 1/8 zoom out).
  Selecting any one of these will cause the drawing to be
  reloaded and the viewed portion of the drawing to be rescaled.
  Remember that throughout all window functions the drawing is
  not being changed, only the viewing window on the drawing.
  When a large drawing is currently being displayed and several
  scaling changes are required, the loading can be stopped and
  the next step effected immediately without waiting for the
  entire drawing to appear.
  Pressing any key or clicking on a function will cause the
  reload to cease and the system will wait for your next
  request.
  Window View Panning
  Panning is a term used to describe the process of stepping
  across the drawing with the viewed screen.
  While in the Window function and not utilizing one of the sub
  functions, if a point is established at a location on the
  drawing, the drawing will then be reloaded with that point as
  the center of the screen.  So if a sequence of points were to
  be established at the right side of the screen, the view will
  be reloaded at each request and each load will pan to the
  right as compared with the previous representation.
  Likewise the view can pan up, down, left or diagonally.
  Again, as it was when scaling the view, upon each reload, the
  process can be stopped by pressing a key or clicking on a
  function.
  The next pan can then be selected without waiting for the
  previous image to finish.
  This is most helpful when large or complicated drawings are
  being manipulated.

  The MOVE function can be invoked by clicking on the word "MOVE" or
  pressing the "F5" key.
  The Move function has three Move sub functions.
  Moving Entities
  The Move sub function allows for the movement of entities to
  other positions in a drawing.
  These movements are limited as necessary by three parameters.
  An asterisk toggled on, next to the ALL DIRECTIONS parameter,
  or the X ONLY parameter, or the Y ONLY parameter, will limit
  movement as described.
  When selected by positioning a point on an entity, the entity
  will follow the cursor in the same relative alignment to the
  point until the new position point is located.
  If multiple elements or entities are to be moved they can be
  moved as a unit by Grouping them together.
  (See
GROUP)
         Procedure
         =========
      -> Step 1. Select the Move sub function from the Move menu.
  POS -> Step 2. Select a point on the entity which is to be moved.
         The position of the point on the entity is irrelevant unless
         it is required by the operator for specific location purposes
         because this point becomes the drag point.
  POS -> Step 3. Locate the new position point by it's drag point as
         should be relative to the entity as it sits in it's new
         location.
  Notice that the entity will follow the cursor about the
  drawing until positioned.
  Upon completion of the movement sequence, four new menu
  selections will appear.
  > MOVE-MOVE-BRING OTHERS  Once a Move sequence has been
    completed, the Bring Others menu option will appear.  If the
    operator then activates the option by selecting it, and an
    asterisk highlights the option, other entities on the drawings
    can be moved as well, all relative to the initial movement.
    For example if an element is moved two inches to the left and
    one inch up, any other entities can be also moved two inches
    to the left and one inch up simply by selecting the Bring
    Others option and the clicking on the desired entities.
  > MOVE-MOVE-EXTEND LINES  When a line is moved and
    vertical or horizontal lines that were connected to that line
    need to be lengthened or shortened to reconnect to the line in
    a similar fashion, the Extend Lines option does so.  Once the
    original line is moved, the Extend Lines option will appear.
    Click on each line which is to be reconnected and it will be
    modified accordingly.
    The lines being extended or trimmed will maintain their
    original vertical or horizontal position.  Only their length
    will be changed.
  > MOVE-MOVE-RECONNECT LINES  When a line is moved and a
    previously connecting line needs to be reconnected, the
    Reconnect Lines option will do so.  Clicking on the Reconnect
    Lines option and following it with selection of the elements
    to be reconnected, will cause the connecting endpoint of the
    line being reconnected to be moved to the point on the moved
    line as it was originally connected.
    The slope of the line being reconnected may change as only one
    endpoint will be moved.
  Moving to a Plumb Line
  The Plumb sub function of the Move function allows the user to
  move an entity horizontally to a plumb vertical axis as
  specified.
         Procedure
         =========
      -> Step 1. Select the Plumb sub function.
  POS -> Step 2. Establish a vertical line to which the entity will be
         aligned.  A vertical ghost line will follow the cursor until
         placed.
  POS -> Step 3. Locate a point on the entity to be moved and the
         entity will be moved such that the point specified intersects
         the plumb line indicator.
  When the entity is selected and therefore moved, the plumb
  line will disappear.
  Note that when selecting the entity to be moved, the point at
  which the entity is identified is important because the entity
  will intersect the plumb line at that point.
  Moving to a Level Line
  The Level sub function allows the user to move an entity to
  align with a level horizontal line.
         Procedure
         =========
       > Step 1. Select the Level sub function of the Move menu.
  POS -> Step 2. Establish a horizontal line to which the entity to be
         moved will be aligned.  A horizontal ghost line will follow
         the cursor until placed.
  POS -> Step 3. Locate a point on the entity to be moved and that
         entity will move such that the point selected will intersect
         the horizontal line as placed.
  When the entity is selected and therefore moved the level line
  will disappear.
  Note that when selecting the entity to be moved, the point at
  which the entity is identified is important because the entity
  will intersect the level line at that point.

Array
Copies
  The Copy function allows an entity to be copied.  This function has
  three sub functions that allow the copies to be either moved,
  rotated or copied following an array pattern.
  You may enter the Copy function by either clicking on the word
  "COPY" on the main menu or pressing "F6" on your keyboard.
  Moving a Copy
  The Move sub function of the Copy menu item is used to copy an
  element or grouped set of elements to form an entity and move
  this copy to another location.
  There are three parameters available to quantify the freedom
  of movement and can be utilized by toggling on the option
  indicated by an asterisk.
  The "ALL DIRECTIONS" parameter allows unrestricted directional
  movement.
  The "X AXIS" parameter limits movement to a horizontal bias
  and "Y AXIS" limits movement to vertical directions.
         Procedure
         =========
      -> Step 1. Select the Copy/Move sub function of the Copy menu.
  POS -> Step 2. Locate a point on the entity to be copied.  It is
         important to pick a point that will be useful in positioning
         the copied entity.
  POS -> Step 3. Locate the copy, which is following the cursor to it's
         final location, using the attachment point as a reference.
  The final location will be precisely relative to the point as
  positioned.
  Once the entity has been moved there will be four extended
  options appearing below the sub function group available for
  the user.
    They are as follows:
  > COPY/MOVE/REPEAT  The Repeat sub option when clicked on
    will duplicate the previous action set.  A new copy will be
    positioned relative to the previous copy as was the previous
    copy to the original.
  > COPY/MOVE/REPEAT COUNT  The Repeat Count sub option is
    an extension of the above described "Repeat".  When clicked on
    and followed by a numerical count factor, the original or
    previous entity will be duplicated as copied and repeated by
    as many times as specified.  Each duplication will be relative
    to the previous copy as was the original copy to the original.
  > COPY/MOVE/REPEAT DISTANCE  The Repeat Distance sub
    option is again similar to both the Repeat and Repeat Count
    options.  This option however requires a distance within which
    copies will be repeated until that point is reached.  Do so by
    selecting Repeat Distance after a copy has been made, then
    selecting the copied element and following it with a distance
    value.  Multiples will then be made to fill the distance as
    identified.
  > COPY/MOVE/COPY OTHER  The Copy Other sub option will
    copy and move a copy of an alternate entity to a position
    relative to it's original as was the copy moved of the
    previous Copy/Move action.  This is done by simply selecting
    any point on an alternate entity and can be repeated for other
    entities in succession.
  Rotating a Copy
  This Copy/Rotate sub function allows the operator to copy an
  entity and rotate it in a specified direction as well an around
  any center.
         Procedure
         =========
      -> Step 1. Select the COPY/ROT sub function.
  POS -> Step 2. Position a point on the object entity to be rotated.
         The location on the element is important because the axis of
         rotation will be around this point unless otherwise specified.
  POS -> Step 2a. Upon selecting an entity the menu item "NEW CENTER"
         will appear.  If this item is selected and followed with a new
         center position on the drawing, it will remain the center
         of rotation until another major sub function is invoked.
  DIR -> Step 3. Specify an angular direction of rotation which will
         determine the direction and amount of rotation around the
         center as indicated.  Positive entry indicates a counter-
         clockwise rotation.
  Once the entity has been rotated there will be four extended
  options appearing below the sub function group available for
  the user.
    They are as follows:
  > COPY/ROTATE/REPEAT  The Repeat sub option when clicked
    on will duplicate the previous action set.  A new copy will be
    positioned relative to the previous copy as was the previous
    copy to the original.
  > COPY/ROTATE/REPEAT COUNT  The Repeat Count sub option is
    an extension of the above described "Repeat".  When clicked on
    and followed by a numerical count factor, the original or
    previous entity will be duplicated as copied and repeated by
    as many times as specified.  Each duplication will be relative
    to the previous copy as was the original copy to the original.
  > COPY/ROTATE/REPEAT ANGLE  The Repeat Angle sub option is
    again similar to both the Repeat and Repeat Count options.
    This option however requires an angle within which copies will
    be repeated until that point is reached.  Do so by selecting
    Repeat angle after a copy has been made, then selecting the
    copied element and following it with an angle degree.
    Multiples will then be made.
  > COPY/ROTATE/COPY OTHER  The Copy Other sub option will
    copy and move a copy of an alternate entity to a position
    relative to it's original as was the copy moved of the
    previous Copy/Rotate action.  This is done by simply selecting
    any point on an alternate entity and can be repeated for other
    entities in succession.
  Creating an Array of Copies
  This Copy Array sub function allows copies to be made and
  arrayed throughout an area in a grid pattern sequence as
  necessary.
  Selection of this menu item causes four information queries to
  appear below.
         Procedure
         =========
  DIST-> Step 1. Select the "ROW SPACE" item and enter a distance
         requested between rows.  A positive entry would notate rows
         above the entity to be copied and likewise a negative entry
         would indicate rows below.
  DIST-> Step 2. Select the "COL SPACE" item and enter a distance
         requested between columns.  A positive entry will identify
         columns to the right of the entity being copied.  A negative
         entry will indicate column spacing of those the left.
      -> Step 3. Select the "ROWS" menu item.  This quantity entry will
         specify the number of copies to be made vertically spaced as
         indicated by the Row Space entry above.
      -> Step 4. Select the "COLS" menu item.  This quantity entry will
         specify the number of copies to be made horizontally spaced as
         indicated in the Col Space area above.
  POS -> Step 5. Identify the entity or entity grouping to be copied
         and arrayed in the pattern as specified.
  The number of Rows multiplied by the number of Cols specified
  will be equal to the number of copies made.
  If numerous or complicated copies are being made, the visual
  representation of the procedure can be halted at any time by
  activating a major function item and the system will accept
  your next commands.

  The GROUP function allows the operator to tag a set of elements or
  entities that will then perform as a single entity when acted upon.
  The group is a temporary collection of elements or entities that is
  affected by utilities such as move, copy, delete or save.
  To enter the Group menu click on the main menu item "GROUP" or
  press "F7".
  The Group menu consists of four sub functions as well as the Window
  View Locator.
  Selecting Elements for the Group
  The Select sub function is used to invite  elements to be part
  of the Group.
  > GROUP-SELECT BLOCK
    The Select Block option will select elements within a defined
    area of the drawing to be part of the Group.  In order to
    define the blocked area, first click on a corner of the object
    area.  A ghost block will follow the cursor at the diagonally
    located corner until it is placed by clicking at a position as
    necessary.
    Note that only totally enclosed non-protruding elements will
    be included in the group.
  > GROUP-SELECT ELEMENTS
    Clicking on each applicable element will cause it to be
    highlighted informing the operator that is has been accepted
    by ProCadd.
    Blocking and individual selection can also be used in
    conjunction.  If for example an area is blocked but a few
    protruding elements do not select.  They can then be
    individually chosen and thereby added to the group.
    Blocking and individual selection can be used in multiple
    succession in order to define items in remote areas of the
    drawing as part of the intended Group.
  Deselecting Elements from the Group
  The Deselect sub function is used to individually remove
  elements from the Group.  Clicking on each undesirable element
  will cause it to be removed.
  Note that blocking an area of the drawing is also applicable
  for deselection.  When the cursor is used to define an area,
  all elements totally enclosed and non-protruding from the
  block will be de selected from the Group.
  Select All for the Group
  The Select All sub function when invoked will select every
  item on the current drawing.  If a large number of elements
  are desired for the Group it may be easier to Select All and
  then Deselect individual or blocks of elements.
  Remember that elements off the viewing screen and elsewhere in
  the drawing will be selected with Select All and be
  manipulated with the Group without being seen.
  Deselect All from the Group
  The Deselect All sub function when invoked will abolish the
  Group completely.
  When this sub function is used the function "RESTORE GROUP"
  will appear beneath the Deselect All sub function.  This will
  restore the group as it was previously in case of a mistaken
  command.

  Whereas the Group functions create temporary groups, the
  Combine function creates permanent ones.
  To enter the Combine sub functions, click on the word "COMBINE" on
  the main menu or press "F8".
  The Combine sub function menu has two options with one parameter as
  well as the Window View Locator.
  Combining for the Group
  The combine sub function builds the group.
  Begin by selecting all of those elements that you wish
  included in the group.  They will disappear temporarily as
  they are selected.
  When you have completed selections follow by clicking on the
  "Combine" sub function menu item.  The elements will reappear
  as a group.
  > COMBINE/ADD TO GROUP  If you wish to add to the Group,
    clicking on "ADD TO GROUP" followed by your selections
    including the group being added to, and finally clicking on
    "COMBINE" will form the combination or Combined Group.
    Whenever selections are being made, two additional menu items
    appear.  "CANCEL" when clicked will abort the entire
    procedure.
    "RESTORE" when clicked will negate the previous selection.
  Separating Elements from the Group
  The Separate sub function dissolves the group as an entity.
  To Separate the Group, select the Group and click on Separate.

Dimensions
  The Dimension function is used to determine and label linear and
  angular dimensions.
  Enter the DIMENSION function by selecting the "DIMENSION" word on
  the main menu or pressing "F9".
  Before we discuss the several Dimension sub functional options we
  will explain the subset of parameters that appear whenever a
  dimension is requested.
    They are as follows:
  > ACCEPT  When a Dimension is requested and sample layout
    and method are indicated on the screen as well as in this
    parameter section, if all is as the operator wishes it to be,
    he would select "ACCEPT" and the Dimension would become
    permanent.
  > CANCEL  If the Dimension is unacceptable and changes
    available are not desired, then "CANCEL" will restart the
    entire sequence.
  > MOVE DIMENSION  The Move Dimension menu item will
    redefine the location of the dimension arrows and labels as
    desired.  The movement is limited however to logical
    positioning relative to the entity being measured.
    Selection of the "MOVE DIMENSION" item will cause the arrow
    and label set to follow the cursor until placed.
  > MOVE LABEL  The Move Label option is used to move the
    Label only to a desired location.  Selecting "MOVE LABEL" will
    cause the dimension's Label to follow the cursor until placed.
  > INTERNAL/EXTERNAL ARROW  The Internal/External Arrow
    toggle determines if the dimension arrows are internally
    pointing at the ends of the dimension or pointing at it from
    the outside.  The type shown will be the type drawn.
  > TEXT EQUALS  The Text Equals item allows the user to
    specify a label size.  When the "TEXT=" selection is made a
    size entry is required by either numeric keyboard or other
    distance facility that appears at the bottom of the menu
    section.
    The program default text size is 0.1 inches of 0.254
    centimeters.
    If some other text size is preferred to be used as a default
    value, it should be entered in the Parameters File as a
    Qualified value.  If the value is unqualified, the value will be
    understood as a factor of the default unit.
    Note that unless the program's text preference is in Real Text
    mode, the text as seen is Fast Text, and not what is plotted.
    The vertical and horizontal half box that surrounds the text is
    the actual height and length of the text as specified.  The
    half box will not plot.  Only the text represented will plot or
    print.
  > ARROW EQUALS  The Arrow Equals option allows the user to
    determine arrow size.  When the "ARROW=" selection is made, a
    size entry is required by either numeric keyboard or other
    distance facility that appears at the bottom of the menu
    section.
    The program default text size is 0.1 inches of 0.254
    centimeters.
    If some other arrow size is preferred to be used as a default
    value, it should be entered in the Parameters File as a
    Qualified value.  If the value is unqualified, the value will be
    understood as a factor of the default unit.
  > UNITS SHOWN  The Units Shown option toggles between
    feet/inches, inches, millimeters, centimeters, meters and
    kilometers.
    Whichever distance units qualifier is present will determine
    the format of the dimension length display.
    The default as displayed is determined in the Parameters File.
  > RESOLUTION EQUALS  The "RESOL.=" menu item when selected
    allows the operator to pick the extent of accuracy to which a
    dimension is displayed.  The default unit, as is displayed
    through this function is determined by the ProCadd Setup
    Parameters File, which can be changed as described in the
    Parameter File description located in Appendix D of
    your manual.
    Clicking on the "RESOL.=" item repeatedly cycles through a
    selection of tolerances both fractional and decimal.
    Note that the Parallel, Horizontal or Vertical sub function
    can measure between two points and not only entities.  When
    selection of the item to be measured is required, respond with
    two point locations on the drawing and ProCadd will calculate
    the distance between them.
  Parallel Dimensions
  The Parallel sub function of the Dimension menu will establish
  a linear dimension set parallel to the distance as specified.
  When the Parallel sub function is activated as evidenced by an
  asterisk, the operator must only select an element or locate
  two points, after which a dimension outline will appear.
  This outline can be either modified or accepted by the subset
  of appliances that appear once the dimension is indicated.
  Horizontal Dimension Components
  The Horizontal sub function, when clicked on and an element is
  chosen, will define the horizontal distance component of that
  element.  An outline of the results and sample display will
  appear for your confirmation.  You can either accept or change
  it.
  Vertical Dimension Components
  The Vertical sub function of the Dimension menu instructs
  ProCadd to calculate the vertical distance component of the
  element selected.  First select "VERTICAL" and follow it with
  the selection of an element.  Then make any necessary
  modifications or accept it as it is.
  Angular Dimensions
  The Angular sub function defines angular dimensions by
  degrees.  ProCadd indicates degree by the "^" sign.
  Since this sub function requires multi positional requests in
  a specific sequence, we will describe it as a procedure.
  Three positional requests will be made.  The order in which
  the points are outlined will determine which side of the angle
  ProCadd measures.
         Procedure
         =========
       > Step 1. Select the Angular sub function.
  POS -> Step 2. Locate a point on the first wing on the structure to
         be measured.  The measurement indicating arrows will arc
         counter-clockwise.  Accordingly if the rightmost wing is
         chosen first then the arrow will measure upward through the
         angle.
         Likewise if the leftmost wing is chosen the label arc will
         radiate downward about the opposite side of the structure.
  POS -> Step 3. Locate the axis of the angle.
  POS -> Step 4. Locate the other wing upon which the dimension profile
         will appear for your approval.
  Note that the point on which the wing is identified will be
  the indication focus of the dimension arrows.
  Angular dimensions of points in free space can be had also
  using the identical procedure only not specifying points on
  elements.
  Radial Dimensions
  The Radial sub function on the Dimension menu is used to
  measure and label radius components of circles and arcs.
  After choosing the Radial menu item, follow with the selection
  of the element to be measured.  An outline of the dimension
  setup will appear for your approval or modification.  The
  dimension arrow will initially appear pointing in the
  direction of the point by which the user specified the element
  to be measured.
  Labeling Dimensions
  The Label sub function is used to assign a label or some
  descriptive text to some portion of the drawing.
  After choosing the "LABEL" option, select a point on the
  drawing toward which the Label arrow should point.
  Notice then how the standard dimension editing features appear
  so that the user can specify and manipulate the Label text as
  desired.
  Once all edit options are as preferred, enter the text.  As
  entered it will be mirrored at the bottom of the screen.
  As with the dimension options, select "ACCEPT" when finished.
  If an arrow only is desired, it is accomplished by completing
  the Label sequence without entering any text.
  Arc Length Dimensions
  The Arc Length sub function is used to measure the
  circumfrential component of a circle or arc.
  Select the "ARC LENGTH" menu item and follow with the
  selection of an element to be measured.  The outline will
  appear for modification or approval.
  Text Editing
  Sub Function -> Text

Inserting
               -> Text
Editing
Moving
  The TEXT function assists in the creation of text as needed.  The
  text can be edited, sized, spaced, colored, rotated, or styled.
  Enter the Text function menu by clicking on the word "TEXT" or
  pressing "F10".
  The Text menu includes two sub functions followed by a group of
  text editing parameters.
  The parameters manipulating the attributes of color and width as
  well as layer designation are available.
  After that are the Window View Locator and the facilities section.
  Editing and Inserting Text
  When Editing existing text select the Edit/Insert sub
  function.
  Begin to Edit by pointing to the text to be edited.  The text
  will appear at the bottom of the screen confirming the edit.
  The attributes menu items will be automatically changed to
  reflect the characteristics of the text in question.  These
  can be changed to suit the operator by pointing to the item
  and inputting new values.
  During modification, the outline of the text will alter
  indicating specified location and orientation.
  Once complete pressing enter will confirm the operation.
  In order to Insert new text, the same process is used except
  that instead of pointing at existing text, the user points out
  a new location.
  The text characteristic variables are listed and described
  below.
  > FAST/REAL TEXT - Clicking on this menu item toggles the
    current selection between Fast and Real text.  Fast text is
    either just an outline of the text to be plotted indicating
    actual height and length or if large enough, a display of the
    text will appear in standard text mode inside the outline of
    the actual text.
    Real Text is an actual Real Scaled representation of the
    text as saved on the drawing including font type and style.
    Normally when using ProCadd and especially when a large
    drawing is current, the Real Text mode would only be used as a
    confirmation or visual tool.
    Because of the taxation of the computer's resources required
    to display Real Text, it is advantageous to keep this menu
    item toggled normally to Fast mode.
  > SIZE EQUALS - Clicking on "SIZE=" will call for a value
    to be the new text height.  This value will be inches with
    decimal notation.
    The program default text size is 0.1 inches of 0.254
    centimeters.  If some other text size is preferred to be used as
    a default value, it should be entered in the Parameters File as a
    Qualified value.  If the value is unqualified, the value will be
    understood as a factor of the default unit.
  > ROTATION EQUALS - The "ROTATION=" variable orients the
    radiated direction of the text in question.  A direction
    request by numeric entry or rose indication will alter the
    text's orientation.
  > SPACING EQUALS - Pointing to the "SPACING=" item will
    prompt a line spacing request.  Enter a value to be understood
    as a measure of the default units of measure depending on
    whether the program is operating in U.S. of metric mode.
    The default spacing is valued at the text size times a factor
    of 1.6667.
    When entering multiple lines of text and the first line is
    confirmed by pressing "enter", the cursor will Space down the
    value as input at this variable and be ready to receive the
    next line's text.
  > LEFT/CENTER/RIGHT JUSTIFIED - The menu items "LEFT" and
    "CENTER" and "RIGHT" toggled when pointed to and followed by
    "JUSTIFIED" indicate a method of alignment for the text as
    entered.
    Left text will extend to the right of the location point.
    Right text similarly to the left and Center text will extent
    equally in both directions as entered.
  > FONT EQUALS - There are two fonts available to the
    ProCadd user in the standard program.  In the "FONT=" variable
    a "0" or a "1" can be entered to choose between them.
    If the user wishes to define additional fonts it can be done
    by referring to Appendix B and placing the font file into the
    /CAD650/fonts directory.
  > NORMAL/BOLD/ITALIC/UNDERLINE - These items will toggle
    in rotation when clicked on.  The text styles of "NORMAL",
    "BOLD", "ITALIC" and "UNDERLINE" will alter AND establish
    the text style to be plotted.
  Moving Text
  The Move Text menu item when pointed at is used to reposition
  text on the drawing.
  This is performed by first selecting the menu item Move Text
  and then pointing to the text to be moved and dragging it to
  it's desired position.

  As well as sectioning an area, the Section function can be used as
  a "fill" function to fill in or shade and color an area.
  Enter the Section function menu subset by pointing and clicking on
  the word "SECTION" or by pressing "F11".  If your key board does
  not support "F11", then "ALT-F7" will substitute.
  The Section function menu has at the top three methods or options
  used to identify the boundaries of the area to be sectioned.
  Below these are three commands used to draw the section lines or
  retract boundary specifications.
  Then there are two variables used to clarify section line spacing
  and section line direction.
  Finally the attribute selection area and the Window View Locator
  are included followed by the facilities section.
  Area Boundary Definition
  These three boundary selection identifiers are in use when an
  asterisk appears by the one clicked on.
  The Entity identifier when used selects entities.  When the
  entity is clicked on it will be highlighted.
  The Element identifier likewise selects elements to be used as
  boundaries.  They also will be highlighted upon selection.
  The Add Point selection device chains together multiple point
  locations in order to create the boundary to be sectioned.
  Lines appear between the points to assist the operator in
  location but upon completion they will disappear.
  Drawing Section Lines
  Upon completion of the desired boundary area or areas, the
  "FILL" command will section the area as identified.
  If modifications to the boundary area are needed prior to
  execution of sectioning, "CANCEL LAST" will remove the
  preceding boundary selection or "CANCEL ALL" will remove all
  boundary selections.
  Section Line Definition
  The Direction and Distance variable requests are used to
  select rotational direction of the sectioning lines as well as
  the spacing distance between them.
  When the user clicks on the Direction variable item a
  direction input is required either by rose selection, numeric
  vector input, or selection of a like element on the drawing
  who's direction can be emulated.
  When the user clicks on the Distance variable item a distance
  input is required.  Enter the distance desired between each
  section line.
  When in metric mode, this entry will represent a centimeter
  measurement and when in U.S. mode, an inch measurement will
  be assumed.
  Deleting Entities
  The DELETE function removes elements or entities from the drawing.
  Access the Delete function by selecting the main menu item "DELETE"
  or by pressing "F12".  If your keyboard does not support "F12" then
  pressing "ALT-F8" will substitute.
  The sole item on the Delete menu is the Window View Locator.
  To Delete an entity just click on the entity.
  Once the entity is removed the command Restore will appear on the
  menu.
  Clicking on "RESTORE" will reverse the previous action and restore
  the entity previously deleted.

Mirroring
Entities
  The Rotate function allows the user to Rotate or Mirror any entity
  or group of entities.
  Enter the Rotate function menu by clicking on "ROTATE" or pressing
  "SHIFT-F1".
  The Rotate menu will appear with two sub functions namely Rotate
  and Mirror followed by a direction variable entry item.
  Then there are the customary Window View Locator and the facilities
  section.
  Rotating an Entity
  This sub function assists the operator in rotating an entity
  by a known angle or relative to another angle and around any
  center.
         Procedure
         =========
      -> Step 1. Select the Rotate sub function from the Rotate menu
         section.  An asterisk will appear at the Rotate menu item as
         notice of it's selection.
  POS -> Step 2. Select the entity or group of entities.  The point by
         which you select the object will be the center around which
         the object will be rotated.
  POS -> Step 2a If a center of rotation other than on the object is
         required, select the "NEW CENTER" menu item and position a new
         center point.
  DIR -> Step 3. Through rose selection or numeric input specify an
         angle of rotation.
  Assuming that the menu item "BEG ANGLE" is zero degrees, the
  object will then rotate in a counter-clockwise direction around
  the center as specified, to an angle relative to it's original
  position by that angle.
  If rotation relative to another entity is required an
  alternate value can be entered for the Beginning Angle.
  Select "BEG ANGLE" and enter a numeric angle or pick an angle
  based on the drawing by positioning two points on the screen.
  ProCadd will determine the angle of the direction of an
  imaginary line between the points from the first to the second.
  Mirroring an Entity
  The Mirror sub function allows the entity or group of entities
  in question to be manipulated such that the image is reversed
  or Mirrored about an axial direction as specified.
         Procedure
         =========
      -> Step 1. Select the Mirror sub function.
  DIR -> Step 2. Select the "MIR.ANG." item on the menu and specify the
         direction of the axis around which the object will be
         mirrored.  If the angle is part of the object or some other
         part of the drawing, then choose two points on that axis and
         ProCadd will display the correct angle.
  POS -> Step 3. Select a mirroring point which can be anywhere on the
         drawing through which the mirroring axis will pass and around
         which the image of the object will reverse itself.
  POS -> Step 4. Pick the object to be mirrored by selecting any point
         on that object.
  Upon selection of the entity being mirrored it will disappear
  from it's current position and reappear opposite and
  equidistant as relative the axis as specified.
  Scaling an Entity
  The Scale function is used to enlarge or reduce the size of any
  entity or group of entities.  This is not the viewed size but the
  actual size.
  Enter the Scale menu by selecting the word "SCALE" from the main
  menu or by pressing "SHIFT-F2" from anywhere within ProCadd.
         Procedure
         =========
  POS -> Step 1. Select the entity or group to be manipulated.
  POS -> Step 1a If the position of the point selecting the entity to
         be manipulated is not the center about which the rescaled size
         of the entity is to center, then select "NEW CENTER" on the
         menu and position a New Center point.
  DIST-> Step 2. Specify a distance either by keyboard entry or by use
         of one of the distance facilities at the bottom of the menu
         section.  This value will be the first or current value in the
         ratio dictating the size adjustment.
  DIST-> Step 3. Specify the second distance required to complete the
         ratio of change by use of keyboard or other facility.  A
         smaller value than the previous step will reduce the entity
         size.  A larger value will increase the entity size.

  The Translate function is a combination of several previously
  described functions.  The Translate function will copy, rotate,
  scale and mirror an entity or group all at the same time.
  To enter the Translate function menu, click on "TRANSLATE" or press
  the "SHIFT-F3" key or keys.
  The Translate function menu has three parameter variables
  controlling scaling, mirroring and rotation.  Following are four
  sub options allowing recentering as well as repeat options and
  translation formats.
  In order to use the Translate function, begin by selecting the
  object or object group to be manipulated.  The point by which the
  object is chosen becomes the placement reference point for the
  copy, as well as the center for the scale, rotation and mirroring.
  If a New Center is required for scale, rotate, and/or mirror then
  after selecting the object, click on "NEW CENTER" and point out the
  New Center as desired.
  Drag the ghost copy of the object being copied and place it as
  necessary.  The permanent copy will appear upon placement,
  referenced by it's drag point and manipulated as the variable
  parameters have dictated.
  A "REPEAT" option is available to make identical copies relative to
  the previous copy as the previous copy was relative to the
  original.
  A "BRING OTHERS" option also appears after the original
  translation.  When clicked on and followed by selection of
  alternate elements, those elements will be treated identically as
  was the original.
  Scaling Translation Parameter
  Set the Scale component of the Translate function.  Select the
  "SCALE=" menu item and follow with two distance entries which
  will represent the scaling ratio of the function.
  If no change in size is required then set the scale to one.
  Rotation Translation Parameter
  Set the Rotation component of the Translate function.  Select
  the "ROTATION=" menu item and enter a Rotation angle which
  will affect the object in a counter-clockwise direction for a
  positive entry.
  If no rotation is required then set this variable to zero.
  Mirroring Translation Parameter
  Set the Mirror component of the Translate function.  Select
  the "MIRROR=" menu item and enter a Mirror axis direction
  which will determine the perspective of the mirrored image.
  If no Mirrored image is required then set this variable to
  zero.
  Drag Image Type Parameter
  The Drag Box or Drag All option determines whether the ghost
  following the placement of the entity or group being
  translocated is a boxed outline of the entity or an image of
  the entity itself.
  If the entity is a complicated subject then it may tax
  your computer's resources in managing duplication of the image
  as it moves across the screen and therefore may slow the
  operator down or misrepresent the entities intended location so
  when the box option is used a simple outline represents the
  more complicated image and therefore is more easily moved.
  Toggle between Drag Box and Drag All as necessary.

  To enter the Attributes menu, click on "ATTRIBUTES" or press
  "SHIFT-F4".
  The Attributes menu has six sub functions used to evaluate or
  change various properties of specific elements of a drawing.
  These are followed by the Attributes status area which works in
  conjunction with the sub functions above.
  Also the Window View Locator is present and finally the facilities
  section.
  Enquiring About Attribute Status
  The Enquire sub function of the Attributes section is used to
  qualify the current display status of elements of a drawing.
  Select the "ENQUIRE" sub function and then the element in
  question.
  The Attribute status section of the menu will then display the
  properties of that element.
  Assigning Layer Status
  The Set Layer sub function is used to reassign layer status to
  a given element or entity.
         Procedure
         =========
      -> Step 1. Select the "LAYER" sub function and only the layer
         selection portion of the Attributes display section will
         appear.
      -> Step 2. Alter the layer to the desired result by cycling up or
         down with the "+" or "-" signs.
  POS -> Step 3. Select the element to be modified and it will be
         changed.
  If more than one element requires the same property, repeated
  selection of alternate elements will change them as well.
  If a mistake is made then clicking on the "RESTORE" command
  will reverse the previous action.
  Line Width Manipulation
  The Set Width sub function is used to alter element width.
  Line widths are assigned to the width selection numbers in the
  Plot section of ProCadd. (See PLOT - Section 10.23)
         Procedure
         =========
      -> Step 1. Select the "WIDTH" sub function.  Only the Width
         portion of the status area will then appear.
      -> Step 2. Alter the current width up or down to the desired
         point.
  POS -> Step 3. Select the object element to be modified.
  If similar changes are required for other elements or entities,
  select them next.
  The "RESTORE" menu item will reverse the previous selection.
  Line Structure Assignment
  The Set Structure sub function of the Attributes menu is used
  to select the line structure type of the element in question.
         Procedure
         =========
      -> Step 1. Select the "STRUCTURE" menu item.  The line structure
         property status will appear in the Attribute status area.
      -> Step 2. Cycle through the eight status options by clicking on
         the sample line element in the status area.  The options are
         assigned in the Plot function menu. (See Plot - Section 10.22)
  POS -> Step 3. Select the object element to be altered.
  Select repeated elements to be changed similarly if desired.
  The "RESTORE" menu command will return the previous elements
  to their previous status.
  Color Assignment
  The Set Color sub function on the Attributes is used to select
  the color of the element in question.
         Procedure
         =========
      -> Step 1. Select the "COLOR" menu item.  The color status bar
         will appear in the Attributes status area.
      -> Step 2. Cycle through the color selections by clicking on the
         color bar and stopping on the desired color.
      -> Step 3. Select each element to be changed to the chosen color.
  The "RESTORE" menu item will reverse the previous action.
  Assignment of All Attributes
  The Set All sub function operates as do all of the individual
  Attribute sub functions except that this one alters more than
  one at a time.  Each item in the status area must be as
  desired because when the element to be modified is selected,
  each property of the element will be altered to be consistent
  with the status area variables.
  First select the "SET ALL" sub function, set the properties
  and finally select the element or elements to be modified.

Defined
  An Ellipse is a circle that is not round.  First we must
  determine the ratio of the length versus the breadth of the
  ellipse and then we must indicate the desired orientation.
  Point and click on the "RATIO" parameter.  This will then
  require two distance entries.  The relationship between these
  two entries will determine the shape of the ellipse.
  An entry of "2" followed by an entry of "1" will create an
  ellipse twice as long as it is wide and will be displayed as a
  ratio of 2.00.
  Point and click on the "SLOPE" parameter.  This will require a
  direction entry that will determine the ellipse's orientation.
  This ellipse's axis which is along the longest possible
  dimension within the ellipse will arrange itself at the slope
  as specified.
  Center,Point Defined Ellipses
  The Center Point option of the Ellipse sub function assists in
  the creation of ellipses by first picking the center and
  following with a point on the perimeter.
              Procedure
              =========
      -> Step 1. Select the "CTR/PT" option of the Ellipse sub
         function.
  POS -> Step 2. Locate a center position for the ellipse being
         created.
  POS -> Step 3. Locate a perimeter position point for the ellipse.
  Note that the orientation of the ellipse is not affected by
  the perimeter location.  The ellipse will be drawn a whatever
  size is necessary to accommodate both the slope parameter and
  the perimeter point.
  Center,Ratio,Rotation Defined
  The Center Ratio Rotation option of the Ellipse sub function
  allows the user to create an ellipse by specifying the center,
  the actual major and minor radial values and the rotation or
  orientation angle.
         Procedure
         =========
      -> Step 1. Select the "CTR/RAT/ROT" option of the Ellipse sub
         function.
  POS -> Step 2. Locate a center position for the ellipse being
         created.
  DIST-> Step 3. Enter by numeric entry or by use of one of the
         facilities at the bottom of the menu both a major and a minor
         radius measurement.  Two separate entries are required.
  DIR -> Step 4. Enter the rotation direction that the ellipse should
         be oriented to.  Enter this variable either by rose or numeric
         angle.
  Concentric Ellipses
  The Concentric sub function of the Ellipse menu creates
  multiple ellipses with the same center.
  This Concentric sub function makes use of the presettable
  slope and ratio variables.
  Point and click on the "RATIO" parameter.  This will then
  require two distance entries.  The relationship between these
  two entries will determine the shape of the ellipse.
  An entry of "2" followed by an entry of "1" will create an
  ellipse twice as long as it is wide.
  Point and click on the "SLOPE" parameter.  This will require a
  direction entry that will determine the ellipse's orientation.
  This ellipse's axis which is along the longest possible
  dimension within the ellipse will arrange itself at the slope
  as specified.
         Procedure
         =========
      -> Step 1. Select the Concentric sub function.
  POS -> Step 2. Locate a center position for the concentric ellipses.
  POS -> Step 3. Locate a perimeter point.
  The ellipse will be drawn upon entry of the perimeter point.
  If the currently displayed slope and ratio are acceptable
  continue on to the second concentric circle by locating a
  perimeter point for the second and repeat until finished.
  Elliptic Arc Drawing
  The Arc sub function of the Ellipse function menu allows the
  user to create elliptic arcs by specifying a center and two
  endpoints.
  This Arc sub function makes use of the presettable slope and
  ratio variables.
  Point and click on the "RATIO" parameter.  This will then
  require two distance entries.  The relationship between these
  two entries will determine the shape of the ellipse.
  An entry of "2" followed by an entry of "1" will create an
  ellipse twice as long as it is wide.
  Point and click on the "SLOPE" parameter.  This will require a
  direction entry that will determine the ellipse's orientation.
  This ellipse's axis which is along the longest possible
  dimension within the ellipse will arrange itself at the slope
  as specified.
         Procedure
         =========
      -> Step 1. Select the "ARC" sub function.
  POS -> Step 2. Locate the radiant center of the arc being created.
  POS -> Step 3. Locate a point to be the beginning point of the
         elliptic arc to be drawn.  Keep in mind that the arc will be
         drawn in a counter-clockwise direction so the endpoint which
         is specified first matters.
  POS -> Step 4. Establish the ending endpoint of the arc.
  Once the second endpoint has been established the arc will be
  drawn.
  Modifying Ellipses and Arcs
  The Modify sub function is used to modify ellipses or
  elliptical arcs.
  Note that when placing new endpoints for the arcs, the
  endpoints should be specified in a counter-clockwise manner.
         Procedure
         =========
      -> Step 1. Select the "MODIFY" sub function of the Ellipse menu.
  POS -> Step 2. Select the element to be modified.  The location of
         the selection point on the element does not matter.
  POS -> Step 3. Locate the first new endpoint on the object arc.
  POS -> Step 4. Locate the other new endpoint on the object arc.
  The arc will be then be drawn in a counter clockwise fashion
  from the first to the second point.

Slopes
  The Spline function enables the operator to draw or modify complex
  curves by selecting a series of points.  The spline line will be
  drawn through the path of points as specified with a logical
  curving shape.
  Since spline curves are not simply mathematically defined but are
  more for appearance, they can be modified or shaped rather than
  requiring them to be totally redefined.
  Enter the Spline set of sub functions by pointing to the main menu
  item "SPLINE" or by pressing "SHIFT-F6".
  The Spline menu has five sub functions used to create and modify
  Splines.
  Also on the menu are the Attribute status area, Window View
  Locator, and the facilities section.
  Creating New Splines
  The New Spline sub function allows the user to create a spline
  by defining two or more points.
  If a mistake is made while points are being defined, the
  previous point can be removed by clicking on "DELETE LAST".
         Procedure
         =========
      -> Step 1. Select the "NEW SPLINE" sub function from the Spline
         function menu.
  POS -> Step 2. Locate the beginning point of the spline curve.
  POS -> Step 3. Locate the second and any further points to be used to
         define the spline curve.
      -> Step 4. Click on "DRAW SPLINE".
  The spline will be drawn from the first point defined to the
  last and will intersect all points between.
  Adding a Point to the Spline
         The Add Point sub function allows the operator to modify a
         spline so that the shape may be defined more precisely by
         inserting an additional point into the spline point path.
         Procedure
         =========
      -> Step 1. Select the "ADD POINT" sub function.
  POS -> Step 2. Select the spline element to which a point is to be
         added.  The location of the identifying point is not of
         consequence.
         Upon selection of the spline, the existing points will appear.
  POS -> Step 3. Position the new point to be added.  The location
         should be between two existing points so that ProCadd can
         identify it's order within the spline point path.
  Upon placement of the new point the spline will be re drawn.
  If the point being added is an endpoint or if the point to be
  added is radically out of line with the existing curve, then
  use "MOVE POINT" after placing the added point in a logical
  path.
  Deleting Points Defining the Spline
  The Delete Point sub function allows the user to modify a
  spline by deleting a point from the group that define that
  spline.
         Procedure
         =========
      -> Step 1. Select the "DELETE POINT" sub function.
  POS -> Step 2. Select the spline from which the point will be
         deleted.  The position of the point identifying the spline
         does not matter.  Once the spline has been selected the
         existing points will appear for reference.
  POS -> Step 3. Point out the point to be deleted and it will
         disappear and the spline will be re drawn.
  Moving Spline Points
  The Move Point sub function allows the user to reshape a
  spline by relocating one of it's identifying points.
         Procedure
         =========
      -> Step 1. Select the "MOVE POINT" sub function.
  POS -> Step 2. Select the spline which is to be modified.  The
         location of the point selecting the spline is not important.
         The existing points will appear upon selection of the spline.
  POS -> Step 3. Click on the point which is to be moved.
  POS -> Step 4. Position the object point at it's new desired
         location.
  Once the new location is defined, the spline will redraw.
  Defining an Endpoint Slope
  The Endpoint Slope sub function is used when a specific slope
  is required at either endpoint of the spline.  This is useful
  when a spline element must make a smooth transition to another
  element.
         Procedure
         =========
      -> Step 1. Select the "ENDPOINT SLOPE" sub function.
  POS -> Step 2. Select the spline to be modified by specifying a point
         on the spline.
  POS -> Step 3. Select the endpoint to be modified.  If an endpoint is
         not defined, then the endpoint nearest to the point used to
         identify the spline will be assumed.
  DIR -> Step 4. Define a slope that the endpoint is to orient to by
         rose, point entry or numeric angle input.
  Once the direction has been determined, the spline will be re
  drawn with it's new endpoint slope.
  Fillet Drawing
  The Fillet function provides the ability to draw a fillet curve at
  the actual or extended intersection of two lines.  The fillet may
  be of any radius.  The lines are automatically modified to end at a
  point of tangency with the fillet curve where it begins and ends.
  Enter the Fillet function menu by selecting the word "FILLET" at
  the main function menu or by pressing "SHIFT-F7".
  The menu contains a Radius dimension variable as well as the
  Attributes section, the Window View Locator and the facilities
  section.
         Procedure
         =========
  DIST-> Step 1. Specify the radius of the Fillet curve by clicking on
         the "RADIUS" menu item and entering a suitable measurement.
         The radius dimension will be qualified as the default units
         of measure depending on the current operation of the program.
         If in metric mode, the radial measurement will be in
         centimeters and when in U.S. mode the default will be inches.
  POS -> Step 2. Select the first of the intersecting lines to which
         the Fillet will connect.  The point of selection although
         itself is not important must be on a portion of the line that
         is being retained.
  POS -> Step 3. Select the other intersecting line to which the fillet
         curve will connect.  This point of selection must also be on a
         portion being retained.
  If the two lines selected are parts of the same entity, the
  resulting fillet curve will also become a part of that entity.
  If however, the two lines are separate entities, the fillet
  will be a separate element on the current layer.
  Any intersecting lines can be connected with a suitable fillet
  curve.  The radius specified must be of a size appropriate for
  the space allowed between the lines.  Parallel lines cannot be
  used.
  Port Creation
  The Ports function creates sole points of attachment on elements or
  entities.  When a Port is assigned to an entity, any effort to
  attach a point to that entity will result in attachment to the
  entity at that Port.
  If a Port is selected on an entity, then the Port becomes part of
  that entity.
  If the Port is selected freely within the drawing and not on an
  entity, then the port will be an entity itself which can be
  Combined to become part of an entity if desired.
  In other words, a Port for an entity does not have to be on that
  entity.
  Ports remain visible on the drawing screen but will not be plotted.
  To enter Ports, go to the Ports menu by clicking on the word
  "PORTS" or press "SHIFT-F8".
  Once at the Ports menu position, the Port or Ports as necessary.
  Once a Port is established on an entity, the Port can be temporally
  disabled but toggling the Ports position facility to "PORTS OFF".
  If multiple ports are desired, the "PORTS OFF" must be toggled to
  at one of the drawing functions.  When Port restrictions are
  enabled, once the first port has been selected, then it is the only
  point of assignment available.

  The Drawing Files section of ProCadd is available to the ProCadd
  user for Drawing File storage, maintenance and retrieval.
  The Structure of File storage is within the \DRAWINGS directory.
  When directories are created, they are done so within the structure
  or directory as is current on the screen.
  When the DRAWINGS directory is displayed, clicking on a XXXX.<DIR>
  will cause that directory to be displayed.
  When in the XXXX directory, clicking on the ".. <DIR>" parent
  directory will return up the tree one step to the DRAWINGS
  directory.
  The Drawing Files menu section is entered by clicking on the main
  menu item "DRAWING FILES" or by pressing "SHIFT-F9".
  Listed throughout Drawing Files, routines are currently specified
  files and directories in a format beginning from left to right and
  including in the first column the file name with the extension.
  Second is the drawing number.  Third is the revision number and
  finally the description.
  The Drawing Files menu section has several options and descriptive
  variables that appear and disappear as appropriate with the
  activation the various sub functions.
    These are:
  > SORT BY NAME/DATE/ASCENDING/DESCENDING/NO SORT  The
    display parameter actually has three sort type variables.
    The first is toggled by clicking on the "SORT" portion of the
    parameter.  The files will either be sorted according to the
    remaining variables or in the case of "NO SORT", be displayed
    in directory order.
    Secondly clicking on the "NAME" or "DATE" sort type will
    toggle between the two and determine the sorted item criteria.
    Finally sorting can be in "ASCENDING" or "DESCENDING" order.
    Clicking on this portion of the variable string will toggle
    between the two.
  > FIND/FIND NEXT  The Find option searches throughout all
    directories and sub directories for any files meeting the
    criteria as specified.  The search is conducted throughout the
    current directory and any sub directories within it.  When
    Find is used Find Next will appear beneath it.  Once the first
    match is located, the find routine will proceed with the
    search when Find Next is selected.
  > FILTER/NO FILTER  When browsing through drawing files,
    the files as displayed can be limited to certain criteria by
    specifying that criteria and toggle the Filter/No Filter to No
    Filter.
    The No Filter option allows for a complete display.
  > CURRENT PATH  The Current Path determines or represents
    the file area being displayed in the display area below.  The
    Current Path can be altered by manually entering the
    [drive]:\[dir]\[dir] or the Current Path will automatically be
    displayed when the directory tree is moved through by mouse.
    Clicking on a directory will take you to that directory and
    clicking on the ".." parent directory sign will back you out.
    In addition, clicking on the actual path specification will
    move the display to that portion of the tree path at which the
    mouse was clicked.
  > FILE NAME  The File Name is the unique DOS file name
    with up to eight characters followed by an extension of three.
    Depending on user preference the file name can be user
    generated or ProCadd generated.  The option of flexible entry
    or ProCadd generated names is decided by a setting in the
    parameter file which you can edit by referring to Appendix D -
    Parameter File Definitions.  When auto generation is active,
    the specification of the Drawing Number and the Revision
    Number will cause ProCadd to assign a File Name.  The File
    Name will be derived from up to the first ten characters of
    the Drawing Number represented by the first eight being the
    file and the other two being the first two of the extension.
    The final character, or the third character of the extension
    will be the first character of the Revision Number.
  > DRAWING NUMBER  The Drawing Number which is chosen by
    the user can be any combination of up to fifteen alphanumeric
    characters long.  The Drawing number must be unique or it will
    overwrite an existing file.
  > REVISION NUMBER  The Revision Number is a two character
    designation.  If a drawing is retrieved and modified, it may
    be advantageous to assign a following consecutive Revision
    Number upon it's resaving.  A unique Revision number will not
    prevent the original file's destruction.  A common Drawing
    Number with a different Revision Number will cause the
    original file to be overwritten when the new revision is
    saved.
  > DESCRIPTION  The Description field is an area where the
    user can identify a drawing with text.  Up to sixty characters
    of text can be entered and will be displayed when browsed.
  Creating a New Drawing
  The New Drawing sub function is used to remove the current
  active drawing and begin a new one.
  Select the "NEW DRAWING" sub function and a blank drawing
  screen will indicate that the objective has been performed.
  Upon selection of a New Drawing, the toggle "U.S. UNITS" or
  "METRIC UNITS" will appear.  The currently displayed option
  reflects the active file format of the previous drawing.
  Changing to an alternate mode will determine the format of the
  drawing as it will be saved only and will not alter the
  current user unit status.
  If by selecting a New File, an important drawing has been lost
  it can at this point be recalled by clicking on "RESTORE".
  Retrieving a Drawing
  The Get Drawing sub function is used to retrieve drawings from
  the archive directories.
  Select the "GET DRAWING" sub function from the Drawing Files
  function menu.
  Use "*.*" for the File Name variable and a complete list of
  files will be displayed in the current directory.  If there
  are more than will fit on the current screen then press "NEXT
  PAGE" and the display will scroll forward.  "PREVIOUS PAGE"
  will scroll back.
  Select the desired file and it will highlight confirming it's
  selection.  The command "GET DRAWING" will appear at the
  bottom of the screen.  Click on it and the drawing indicated
  will be retrieved.
  Combining Drawing
  Once a drawing is currently active, ProCadd can use the
  Combine Drawing sub function to recall an additional drawing
  and overlay it upon the first.
  Use the current drawing or retrieve a drawing from the library
  to be the first of two drawings to be combined.  Select the
  Combine Drawing sub function and operate it the same as the
  Get Drawing sub function by pointing out the file of interest
  to be combined and click on "COMBINE DRAWING" at the bottom of
  the screen.
  The second drawing will be combined with the first.  Initially
  the second drawing will be displayed as a single Group until
  accepted by moving on to another ProCadd function.
  Storing Drawing Files
  The Save Drawing function allows the operator to store
  drawings or Groups from within a drawing for later reference.
  (See
GROUP)
  When saving a drawing or group, the user can assign a name,
  number and revision to the current drawings being saved.
  If desired, ProCadd will derive a File Number from the Drawing
  Number and Revision.
  If the drawing being saved is an updated version of a drawing
  previously retrieved, then normally a new revision number would
  be assigned to it and when stored as ProCadd will warn you,
  the original will be overwritten.
  The original drawing's identity will be displayed as a
  reference for you to note.
  A unique Drawing Number causes non destructive storage but a
  unique Revision Number will overwrite a drawing with a like
  Drawing Number.
  When you save your drawing, the Entity File is copied in it's
  current status to a place and file name as directed.  If the
  file name already exists, then the file being overwritten is
  renamed to [filename].bak.
  The user must determine where the drawing is to be stored.
  Moving through the directory structure within the Drawings
  directory will display their contents.  The Drawing will be
  saved in the current directory as displayed.
  When the drawing being saved has been satisfactorily
  identified for storage and the directory location is present,
  clicking on "SAVE DRAWING" at the bottom of the screen will
  initiate storage.
  If there is an active Group then the information "ONLY THE
  GROUP WILL BE SAVED" will be displayed at the bottom of the
  screen.
  Deleting Drawing Files
  Drawing Files can be deleted as necessary by selecting the
  Delete sub function.
  Once at the Delete sub function section, the files in the
  current directory will be listed.  The directory can be
  changed or if the object for deletion is in the current
  directory, it can be identified by pointing it out at which
  time it will be highlighted for confirmation.
  Clicking on the "DELETE FILE" phrase at the bottom of the
  screen will complete the action.
  Creating Drawing Storage Directories
  The Create Directory sub function is used to create storage
  area directories where necessary.
  After selecting the Create Directory sub function, move to the
  directory into which a sub directory is to be created.
  Specify the new directory name as will be displayed in the
  File Name area.
  Click on the "CREATE DIRECTORY" phrase at the bottom of the
  screen and the action will be complete.
  Deleting Drawing Storage Directories
  The Delete Directory sub function is used to destroy storage
  area directories.
  Prior to deletion, the directory must be empty of all files or
  sub directories.
  In order to delete the object directory, first select the
  Delete Directory sub function.
  Then move to the directory to be deleted.
  Finally click on the "DELETE DIRECTORY" phrase at the bottom
  of the screen.

  The PLOT function outputs the active drawing to a plotter.
  Enter the Plot function menu by selecting "PLOT" on the main
  function menu or by pressing "SHIFT-F10".
  The Plot function menu appears on the screen which contains Plot
  control options available to the user in defining the plot.
  Once all of the options are as desired then "START PLOT" will begin
  the drawing.
  The plot can be interrupted by pressing any function key.
  Only the active Layers will be plotted and likewise if there is an
  active Group as a warning will inform the user "ONLY THE GROUP WILL
  BE PLOTTED".
  Pen Color Specification
  The color samples as displayed on the screen represent the
  colors as available to the user when drawings are created.
  The number of colors available is determined by the Parameters
  file in the Session directory and is default set to the maximum
  sixteen.  If for administrational purposes, the program should
  limit users to a lesser selection, the availability can be
  altered.  See the Parameter File Definitions - Appendix D.
  The Pen Color Section allows the user to assign the output
  colors from the drawing to pen numbers of the plotter.
  To assign pen numbers to drawing colors simply select the
  color and enter the pen number.
  If your plotter is multi penned then ProCadd will
  automatically select a new pen as they have been assigned to
  the drawing.
  If your plotter is a single pen plotter and multiple colors
  have been selected, ProCadd will plot only pen one first.
  Then ProCadd will halt the plot and prompt the user to insert
  pen color two and so on until all colors have been plotted.
  Line Structure Specification
  Shown in the Line Structure Selection section of the Plot
  control screen are seven Line Structures.  These structures
  are the selections available in the Attributes section of
  various ProCadd drawing functions to create elements with.
  Here in the Plot section is where they are defined.(The
  defaults are specified in the Parameters File)  If a line
  structure here is modified then any elements drawn with that
  structure on the current drawing will be modified to the new
  structure specifications.  Also if any other drawings loaded
  while that structure position has it's new definition, they
  will also be modified.
  In this Line Structure Selection section the sample structures
  are listed with the sample line followed by the description of
  that structure.  The method of describing a structure is by
  specifying segment lengths and space lengths until one
  complete description of the structure cycle has been
  described.
  For example: .35,.1,.25,.1  This definition describes a
  structure beginning with a length of .35 followed by a .1
  space, then a .25 segment and another .1 inch space.
  This represents one structure cycle and the line will repeat
  this cycle throughout it's length.(See Appendix D Parameter
  File Definitions for exact procedure)
  In order to modify a structure, use the mouse or the arrow
  keys to move to the structure to be modified.  Then use text
  entering technique in order to define the new structure with a
  comma between each length.
  Note that the format and value possibilities have certain
  limits and these must be followed to correctly define
  structures.  See Appendix D for exact definitions.
  If the user selects a scaling factor for the plot, the line
  length will be scaled but the structure specifics will not.
  (See
SCALING)
  Line Width Specification
  The Line Widths Selection section is where the operator
  determines the option specifications of the line widths in the
  Attributes section and therefore on the plot.
  Listed in this section there are eight line width selections.
  These existing default widths are specified in the Parameters
  File.  See Appendix D for default specifics.  The width
  selected is the physical width in inches.  Also if the drawing
  is scaled then the line widths will not be scaled.
  When the settings are altered, any lines drawn with that width
  selection will be re drawn with the new setting as well as any
  other drawings loaded from memory.
  Wide lines are plotted by multiple pen strokes.  If a line
  width is listed as 0.0 then the pen will draw one stroke.
  To change line widths select the width to be changed with the
  arrow keys or the mouse and enter the new decimal width value.
  Drawing Scale Definitions
  This section of Drawing Scales allows the user to predefine
  and choose from a group of scales to which the drawing will be
  plotted.  The predefined selections are determined by the
  Parameter File default settings. (See Appendix D in your manual)
  By clicking on the desired preset scale, the plot sizes and
  scale listed below on the plot menu will change accordingly.
  If one of these Default Drawing Scales does not suit the user
  then he can change it at the parameter entitled "SCALE=".
  Here a value can be entered.  An entry of .10 would determined
  that the drawing scale would be one tenth.
  The scale can be automatically selected by ProCadd to "best
  fit" to the paper size as selected by clicking on the menu item
  "FIT TO PAPER".  This menu item is, since it would be assumed
  to be most likely used, the default selection.
  Paper Size and Orientation Specifications
  Paper Size for the plot can be defined by selection here.
  Click on this item and the size selection will cycle through
  five options being "A" through "E".
    The physical paper sizes are as follows:
             A = 8.5" x 11"
             B =  11" x 17"
             C =  17" x 22"
             E =  34" x 44"
  The Paper Orientation is toggled between Portrait and
  Landscape.  Click on this item and select whichever is
  appropriate.
  Plotter Device Definition
  The Device parameter informs ProCadd of the plotter type to
  be driven.  A two character plotter designation inserted at
  the "DEVICE=" position will determine the identity of the
  device.
  The device drivers are located in the CAD650\Plotters
  directory.  (See Appendix D in your manual for availability of
  selections.)
  Plot Size Definitions
  Once a Scale has been selected either through one of the
  preset Default Scales or by the direct Scale entry, the Plot
  Width and Plot Height will automatically change, reflecting the
  actual size that drawing to be plotted will be.  This will
  assist the user in paper size selection.
  If a specific scaled size is known or required, it can be
  directly entered and the Scale will automatically adjust to
  accommodate the size as entered.
  In order to enter a pre determined Plot Height or Plot Width ,
  select the item to be changed and enter the new value.
  Plot Margins
  The Top, Bottom, Left and Right Margins are selectable by
  clicking on that item to be changed and entering the new
  Margin value.
  The default in these variables are determined by entry in the
  Plotter Driver Files.  See Appendix E of your manual for parameter
  entry and definition.

Origin
  The Drawing function allows the user to rescale or adjust the
  origin of the current drawing.
  Enter the Drawing menu by clicking on the word "DRAWING" or
  pressing the "SHIFT-F11" key.  If your keyboard will not support
  the "F11" key, "ALT-F9" will substitute for "SHIFT-F11".
  Note that scale and origin changes are not permanent.  They are
  only for the current execution of ProCadd.
  Setting Drawing Scale
  The Set Scale sub function allows the user to scale up or down
  the current drawing.
         Procedure
         =========
      -> Step 1. Select the Set Scale sub function.
  DIST-> Step 2. Use a distance facility to enter a value to become the
         first of two in the scaling ratio.
  DIST-> Step 3. Enter the second distance for the scaling ratio.
  The size of the elements in the drawing as they appear on
  screen will not change, however their measured size will change
  as the ratio determines.
  Existing dimension descriptions will not change and will have
  to be re measured if necessary.
  The current scale status will remain and will affect all
  drawings until changed or until ProCadd is ended and restarted.
  Setting Drawing Origin
  The Set Origin sub function allows the user to reassign the
  origin or real center of the drawing.
  The real center is the 0-X,0-Y graphic center of the drawing
  and may need to be realigned temporally in order to assist the
  user in working within a specific area of the drawing.
  This change is only temporary and will be reassigned as
  original when the current execution of ProCadd is ended.  In
  other words when ProCadd is exited and restarted.
  Exiting ProCadd
  The Exit function ends the current ProCadd execution.
  Exit by clicking on "EXIT" or pressing "SHIFT-F12".  If your
  keyboard does not support "F12", pressing "ALT-F10" will
  substitute for "SHIFT-F12".
  The drawing currently active on the screen will automatically be
  stored as the Active Drawing and will be reloaded upon re-entering
  ProCadd.
  The storage of the Active Drawing is not permanent storage in the
  Drawing Library.  This must be accomplished through the Save
  Drawing sub function of the Drawing Files function menu.

Symbols
  Symbols are commonly used graphic representations which can be
  stored in a Symbols Library and recalled and inserted as desired.
  The Symbols menu is available to the ProCadd user at any time and
  is accessed by pressing "CTRL-F4".
  The Symbols menu will appear with a set of symbol sub functions
  useful in the creation, storage, retrieval and deletion of Symbols.
  Beneath these are the options and parameters which appear when
  applicable and are used to aid the user is manipulating the symbol
  drawing.
    These assorted options are described as follows:
  > SCALE EQUALS - At the Scale Equals variable the user
    can determine at which scale the Symbol in question will be
    inserted in the drawing.  The Symbol is saved in a size as it
    was originally drawn and may need to be sized for the current
    application.
    Upon selecting the Scale Equals item two distance requests
    should follow representing a ratio to affect the symbol when
    inserted.
  > ROTATION EQUALS - The Rotation variable allows the
    operator to enter the Symbol into the drawing at a rotation as
    desired.  At this variable enter a rotation angle or use the
    rose to select a value.
  > MIRROR EQUALS - The Mirror parameter allows the user
    to reverse the image along an axis through the symbol's origin
    which is sloped at any orientation.  Once the Mirror item is
    selected, an orientation angle needs to be entered numerically
    or by use of the rose.
  > DRAG BOX/ALL - The Drag option toggles between Box and
    All.  When on Box, the Symbol being manipulated will be
    represented when moved by an outline box.  This is
    particularly useful when the symbol is complicated and
    resources need be conserved.
    When the Drag All toggle is present, an image of the entire
    symbol will be continuously reproduced as the symbol is moved
    until placed.
  > SHOW AS SAVED/NAME ONLY - While in the Symbols
    function, the symbols in the current Symbol File and on the
    current page are shown at the bottom of the screen.  "AS
    SAVED" means that the image of the symbol picture will
    represent the symbol.  A Symbol would normally be saved as a
    picture with a name, however, if it was saved as a name, "AS
    SAVED" will display the name.
    When "NAME ONLY" is present, only the Symbol's name will be
    present to represent the symbol.
  > PICTURE - When creating and saving a drawing, if the
    item picture is selected evidenced by a asterisk, then an
    image of the symbol being saved will appear in the symbol
    selection area at the bottom of the screen.
  > NAME EQUALS - If the user wishes to name the Symbol,
    it can be done at the "NAME=" item.  Text can be entered
    up to ten characters.  If a name is not specified, the Symbol
    will be called "NONAME".
  > PAGE UP/DOWN - By clicking on the plus or minus sign
    the symbol selection will scroll through the pages of the
    current Symbol File.  Up to 384 pages are allowed in each
    file.
  > NEW ORIGIN - When creating a Symbol, a New Origin to
    be used as a drag and placement point may be preferred as
    opposed to the standard center.
  Entering a Symbol in a Drawing
  When a Symbol is to be inserted in a drawing, it is done by
  simply dragging to it's desired location.
          Procedure
          =========
       -> Step 1. Select the Enter Symbol sub function.
       -> Step 2. Review the available placement and orientation
          parameters and adjust as necessary.
       -> Step 3. Locate and select the object Symbol by clicking on
          the representation.
   POS -> Step 4. Position the Symbol where desired in the drawing.
   POS -> Step 5. Repeat Step 4 and place as many copies of the object
          Symbol as desired.
  Placement of the Symbol will be centered around the origin of
  the Symbol as it was saved.
  Creating a Symbol
  The creation of a Symbol is begun by first drawing that
  Symbol using standard drawing functions.  Once complete, it can
  be stored in a designated Symbol File and with any name.
  Also any portion of an existing drawing that would be
  repeatedly used can be saved as a Symbol and recalled as
  necessary.
          Procedure
          =========
       -> Step 1. Using standard ProCadd drawing procedures, create the
          Symbol to be saved or Combine a group to be saved.
       -> Step 2. Select "CREATE SYMBOL" from the Symbol function menu.
       -> Step 3. Select the entity or group to be saved as a Symbol.
          Note that only a permanent "Combined" group can be saved as a
          symbol set.
          Upon selection of the Symbol, an origin point will appear at
          the center of the Symbol set.  At this time a new origin can
          be specified by selecting "NEW ORIGIN" and following with a
          New Origin point position.
       -> Step 4. Select a name for the Symbol and whether or not it is
          to be saved as a Picture.
       -> Step 5. Select the location at which the Symbol is to be
          saved and click on that location point.
  It is recommended that the Symbol be saved with both a name
  and a picture by first entering a name and following up by
  selecting picture for the creation.  The name can always be
  displayed if desired by selecting "SHOW NAME ONLY".
  Deleting a Symbol
  Symbols can be deleted by selecting the "DELETE SYMBOL" sub
  function and then pointing to the Symbol to be deleted.
  Subsequent symbols can be then selected and deleted as well.
  Deleting a Page of Symbols
  Entire pages of symbols can be deleted by paging to the one
  targeted for deletion and then selecting "DELETE PAGE".
  There will be a confirmation required which can be done by
  selecting on "DELETE THIS PAGE".
  Deleting All Symbols in a File
  Selecting the Delete All sub function will cause the entire
  active Symbol File to be deleted.
  The option "RESTORE" appears if perhaps the deletion should
  be reversed.

  Symbol Files are where Symbols are stored.  Each file can hold one
  or hundreds of symbols and each file can be stored in any directory
  as desired.
  Enter the Symbol Files function menu by pressing "CTRL-F5".
  The structure of File storage is within the \SYMBOLS directory.
  When directories are created they are done so within the structure
  or directory as is current on the screen.
  When the SYMBOLS  directory is displayed, clicking on a XXXX.<DIR>
  will cause that directory to be displayed.
  When in the XXXX directory, clicking on the ".. <DIR>" parent
  directory will return up the tree one step to the SYMBOLS
  directory.
  Listed throughout Symbols Files routines are currently specified
  files and directories in a format beginning from left to right and
  including in the first column, the file name with the extension.
  Second is the drawing number.
  Third is the revision number and finally the description.
  The Symbols Files menu section has several options and descriptive
  variables that appear and disappear as appropriate with the
  activation the various sub functions.
    These are:
  > SORT BY NAME/DATE/ASCENDING/DESCENDING/NO SORT  The
    display parameter actually has three sort type variables.
    The first is toggled by clicking on the "SORT" portion of the
    parameter.  The files will either be sorted according to the
    remaining variables or in the case of "NO SORT", be displayed
    in directory order.
    Secondly, clicking on the "NAME" or "DATE" sort type will
    toggle between the two and determine the sorted item criteria.
    Finally sorting can be in "ASCENDING" or "DESCENDING" order.
    Clicking on this portion of the variable string will toggle
    between the two options.
  > FIND/FIND NEXT  The Find option searches throughout all
    directories and sub directories for any files meeting the
    criteria as specified.  The search is conducted throughout the
    current directory and any sub directories within it.  When
    Find is used Find Next will appear beneath it.  Once the first
    match is located, the find routine will proceed with the
    search when Find Next is selected.
  > FILTER/NO FILTER  When browsing through symbol files,
    the files as displayed can be limited to certain criteria by
    specifying that criteria and toggle the Filter/No Filter to No
    Filter.
    The No Filter option allows for a complete display.
  > CURRENT PATH  The Current Path determines or represents
    the file area being displayed in the display area below.  The
    Current Path can be altered by manually entering the
    [drive]:\[dir]\[dir], or the Current Path will automatically be
    displayed when the directory tree is moved through by mouse.
    Clicking on a directory will take you to that directory and
    clicking on the ".." parent directory sign will back you out.
    In addition, clicking on the actual path specification will
    move the display to that portion of the tree path at which the
    mouse was clicked.
  > FILE NAME  The File Name is the unique DOS file name
    with up to eight characters followed by an extension of three.
    Depending on user preference the file name can be user
    generated or ProCadd generated.  The option of flexible entry
    or ProCadd generated names is decided by a setting in the
    parameter file which you can edit by referring to Appendix D -
    Parameter File Definitions.  When auto generation is active,
    the specification of the File Number and the Revision
    Number will cause ProCadd to assign a File Name.  The File
    Name will be derived from up to the first ten characters of
    the File Number represented by the first eight being the
    file and the other two being the first two of the extension.
    The final character or the third character of the extension
    will be the first character of the Revision Number.
  > FILE NUMBER  The Drawing Number which is chosen by the
    user can be any combination of up to fifteen alphanumeric
    characters long.  The file number must be unique or it will
    overwrite an existing file.
  > REVISION NUMBER  The Revision Number is a two character
    designation.  If a file is retrieved and modified, it may be
    advantageous to assign a following consecutive Revision Number
    upon it's resaving.  A unique Revision number will not prevent
    the original file's destruction.  A common File Number with a
    different Revision Number will cause the original file to be
    overwritten when the new revision is saved.
  > DESCRIPTION  The Description field is an area where the
    user can identify a drawing with text.  Up to sixty characters
    of text can be entered and will be displayed when browsed.
  Retrieving a Symbol Set
  The Get Symbol Set sub function is used to retrieve Symbol
  Files from the archive directories.
  Select the "GET SET" sub function from the Symbol Files
  function menu.
  Use "*.*" for the File Name variable and a complete list of
  files will be displayed in the current directory.  If there
  are more than will fit on the current screen, then press "NEXT
  PAGE" and the display will scroll forward.  "PREVIOUS PAGE"
  will scroll back.
  Select the desired file and it will highlight, confirming it's
  selection.  The command "GET FILE" will appear at the bottom
  of the screen.  Click on it and the Symbol File indicated will
  be retrieved.
  Combining Symbol Sets
  Once a Symbol Set is currently active, ProCadd can use the
  Combine Set sub function to recall an additional Symbol Set and
  overlay it upon the first.
  Use the current Symbol File or retrieve a file from the
  library to be the first of two files to be combined.  Select
  the Combine Set sub function and operate it the same as the
  Get Set sub function by pointing out the file of interest to
  be combined and click on "COMBINE DRAWING" at the bottom of
  the screen.
  The second Symbol File will be combined with the first.
  Saving a Symbol Set
  The Save Set function allows the operator to store symbol
  files for later reference.
  When saving a file, the user can assign a name, number and
  revision to the current Symbol Set being saved.
  If desired, ProCadd will derive a File Number from the File
  Number and Revision.
  If the Symbol File being stored is an updated version of a
  file previously retrieved, then normally a new revision number
  would be assigned to it and when stored as ProCadd will warn
  you, the original will be overwritten.
  The original file's identity will be displayed as a reference
  for you to note when specifying the number to store.
  A unique File Number causes non destructive storage but a
  unique Revision Number will overwrite a Symbol File with a
  like File Number.
  When you save your Symbol Set, the Entity File is copied in
  it's current status to a place and file name as directed.  If
  the file name already exists, then the file being overwritten
  is renamed to [filename].bak.
  The user must also identify where the file is to be stored.
  Moving through the directory structure within the Symbols
  directory will display their contents.  The Symbol File will
  be saved in the current directory as displayed.
  When the file being saved has been satisfactorily identified
  for storage and the directory location is present, clicking on
  "SAVE SET" at the bottom of the screen will initiate storage.
  Deleting a Symbol File
  Symbol Files can be deleted as necessary by selecting the
  Delete File sub function.
  Once at the Delete sub function section, the files in the
  current directory will be listed.  The directory can be
  changed or if the object for deletion is in the current
  directory it can be identified by pointing it out, at which
  time it will be highlighted for confirmation.
  Clicking on the "DELETE FILE" phrase at the bottom of the
  screen will complete the action.
  Creating a Symbol Directory
  The Create Directory sub function is used to create storage
  area directories where necessary.
  After selecting the Create Directory sub function, move to the
  directory into which a sub directory is to be created.
  Specify the new directory name as will be displayed in the
  File Name area.
  Click on "CREATE DIRECTORY" phrase at the bottom of the screen
  and the action will be complete.
  Deleting a Symbol Directory
  The Delete Directory sub function is used to destroy storage
  area directories.
  Prior to deletion the directory must be empty of all files or
  sub directories.
  In order to delete the object directory first select the
  Delete Directory sub function.
  Then move to the directory to be deleted.
  Finally click on the "DELETE DIRECTORY" phrase at the bottom
  of the screen.

  The Standard Parts function menu is available by pressing "CTRL-
  F6".
  The Standard Parts menu includes five sub functions as well as the
  Window View Locator.
  First we will explain the standard parameter options used to
  identify the parts drawings being stored or retrieved.
    These are:
  > SORT BY NAME/DATE/ASCENDING/DESCENDING/NO SORT  The
    display parameter actually has three sort type variables.
    The first is toggled by clicking on the "SORT" portion of the
    parameter.  The files will either be sorted according to the
    remaining variables or in the case of "NO SORT", be displayed
    in directory order.
    Secondly clicking on the "NAME" or "DATE" sort type will
    toggle between the two and determine the sorted item criteria.
    Finally sorting can be in "ASCENDING" or "DESCENDING" order.
    Clicking on this portion of the variable string will toggle
    between the two options.
  > FIND/FIND NEXT  The Find option searches throughout all
    directories and sub directories for any files meeting the
    criteria as specified.  The search is conducted throughout the
    current directory and any sub directories within it.  When
    Find is used Find Next will appear beneath it.  Once the first
    match is located, the find routine will proceed with the
    search when Find Next is selected.
  > FILTER/NO FILTER  When browsing through symbol files,
    the files as displayed can be limited to certain criteria by
    specifying that criteria and toggle the Filter/No Filter to No
    Filter.  The No Filter option allows for a complete display.
  > CURRENT PATH  The Current Path determines or represents
    the file area being displayed in the display area below.  The
    Current Path can be altered by manually entering the
    [drive]:\[dir]\[dir] or the Current Path will automatically be
    displayed when the directory tree is moved through by mouse.
    Clicking on a directory will take you to that directory and
    clicking on the ".." parent directory sign will back you out.
    In addition, clicking on the actual path specification will
    move the display to that portion of the tree path at which the
    mouse was clicked.
  > FILE NAME  The File Name is the unique DOS file name
    with up to eight characters followed by an extension of three.
    Depending on user preference the file name can be user
    generated or ProCadd generated.  The option of flexible entry
    or ProCadd generated names is decided by a setting in the
    parameter file which you can edit by referring to Appendix D -
    Parameter File Definitions.  When auto generation is active,
    the specification of the File Number and the Revision
    Number will cause ProCadd to assign a File Name.  The File
    Name will be derived from up to the first ten characters of
    the File Number represented by the first eight being the
    file and the other two being the first two of the extension.
    The final character or the third character of the extension
    will be the first character of the Revision Number.
  > FILE NUMBER  The Drawing Number which is chosen by the
    user can be any combination of up to fifteen alphanumeric
    characters long.  The file number must be unique or it will
    overwrite an existing file.
  > REVISION NUMBER  The Revision Number is a two character
    designation.  If a file is retrieved and modified, it may be
    advantageous to assign a following consecutive Revision Number
    upon it's resaving.  A unique Revision number will not prevent
    the original file's destruction.  A common File Number with a
    different Revision Number will cause the original file to be
    overwritten when the new revision is saved.
  > DESCRIPTION  The Description field is an area where the
    user can identify a drawing with text.  Up to sixty characters
    of text can be entered and will be displayed when browsed.
  Retrieving a Parts File
  The Get Part sub function is used to retrieve part drawings
  from the archive directories.
  Select the "GET PART" sub function from the Standard Parts
  function menu.
  Use "*.*" for the File Name variable and a complete list of
  files will be displayed in the current directory.  If there
  are more than will fit on the current screen then press "NEXT
  PAGE" and the display will scroll forward.  "PREVIOUS PAGE"
  will scroll back.
  Select the desired file and it will highlight confirming it's
  selection.  The command "GET FILE" will appear at the bottom
  of the screen.  Click on it and the Parts Drawing indicated
  will be retrieved.
  Combining a Part into a Drawing
  When a part is desired to be placed in a drawing, it is first
  retrieved using "GET PART".
  Once the part is loaded, an additional menu item will appear
  called "COMBINE PART".
  By clicking on the Combine Part menu item, the just retrieved
  part will be combined with the active drawing as was being
  worked with when Standard Parts was entered.
  The part will be placed in the drawing, centered, and as a
  Group.  It can then be manipulated with it's Grouped status
  until placed as desired.
  A Parts Drawing would typically show alternate view angles of
  the part with related information and dimensions.  In this case
  only a portion of the drawing would be desired to be entered in
  the active drawing.  Once the part is loaded and available, a
  portion of the parts drawing can be selected with the mouse and
  they will be highlighted indicating acceptance to form a group.
  This group will be combined with the active drawing when
  clicking on "COMBINE PART".  An alternate method of specifying
  the grouped portion of the Parts Drawing to be combined with
  the Active Drawing is to block it with the mouse.
  Clicking on a point of the Part Drawing and sweeping diagonally
  and clicking again will block a portion of the drawing to be
  grouped and combined.
  Note that only totally included non-protruding elements will be
  selected for the group.  Other elements can be selected
  individually.
  Storing a Parts File
  The Save Part function allows the operator to store part files
  or a Group from within a drawing as a Parts File for later
  reference. (See
GROUP)
  When saving a file or a Group as a file, the user can assign a
  name, number and revision to the current Part Drawing being
  saved.
  If desired, ProCadd will derive a File Number from the Part
  Drawing Number and Revision.
  If the Part File being stored is an updated version of a file
  previously retrieved then normally a new revision number would
  be assigned to it and when stored as ProCadd will warn you,
  the original will be overwritten.
  The original file's identity will be displayed as a reference
  for you to note.
  A unique File Number causes non destructive storage but a
  unique Revision Number will overwrite a Part Drawing with a
  like File Number.
  When you save your Parts Drawing, the Entity File is copied in
  it's current status to a place and file name as directed.  If
  the file name already exists, then the file being overwritten
  is renamed to [filename].bak.
  The user must also identify where the file is to be stored.
  Moving through the directory structure within the STDPARTS
  directory will display their contents.  The Part Drawing will
  be saved in the current directory as displayed.
  When the file being saved has been satisfactorily identified
  for storage and the directory location is present, clicking on
  "SAVE PART" at the bottom of the screen will initiate storage.
  If there is an active Group then the information "ONLY THE
  GROUP WILL BE SAVED" will be displayed at the bottom of the
  screen.
  Deleting a Parts File
  Parts Drawing Files can be deleted as necessary by selecting
  the Delete File sub function.
  Once at the Delete sub function section, the files in the
  current directory will be listed.  The directory can be
  changed or if the object for deletion is in the current
  directory it can be identified by pointing it out, at which
  time it will be highlighted for confirmation.
  Clicking on the "DELETE FILE" phrase at the bottom of the
  screen will complete the action.
  Creating a Parts File Directory
  The Create Directory sub function is used to create storage
  area directories where necessary.
  After selecting the Create Directory sub function, move to the
  directory into which a sub directory is to be created.
  Specify the new directory name as will be displayed in the
  File Name area.
  Click on "CREATE DIRECTORY" phrase at the bottom of the screen
  and the action will be complete.
  Deleting a Parts File Directory
  The Delete Directory sub function is used to destroy storage
  area directories.
  Prior to deletion the directory must be empty of all files or
  sub directories.
  In order to delete the object directory first select the
  Delete Directory sub function.
  Then move to the directory to be deleted.
  Finally click on the "DELETE DIRECTORY" phrase at the bottom
  of the screen.
  At any time while in ProCadd, On Line Help is available to the
  user complete with all major function descriptions as well as
  a handy function key assignment table upon entering.
  To enter the help sections click on the Help option at any
  menu or press "Ctrl-F1".
  When entering the Help menus, the program will remain resident
  in order to facilitate a speedy transfer to and from the Help
  menus.
  If however, your system is too over burdened with resident
  operations, ProCadd will notify you an unload before bringing
  up the Help menu.  Upon exiting the help section, ProCadd will
  automatically reload.
  Once at the Help menu, double click on the highlighted menu
  item of interest and help on the appropriate topic will
  appear.
  Note: If you need assistance in tidying up your operating
  system and minimizing your resident requirements so that the
  Help files will run resident, please refer to your manual.
  ProCadd will shell to DOS while remaining resident as a
  convenience to the operator.
  At any time the user can type "EXIT" and ProCadd will return.
  Shell to DOS by typing "Ctrl-F2".
  Press "Ctrl-F3" while anywhere within the program and ProCadd's
  Status will display at the bottom of the screen.
  The program name will display followed by the release and
  version number.  Then the serial number of your program will
  appear and finally will be the available base memory.
  Pressing "Ctrl-F3" will also play a sample of the system prompts
  as described and defined in the parameters file.  See APPENDIX D
  - Parameter File Definitions in your manual for an explanation.
