*********************** LINEAR COPY ************************
LINEAR COPY FUNCTIONS COPY ELEMENTS IN A STRAIGHT LINE WHERE
THE COPIES ARE EQUALLY SPACED APART. IN THIS TUTORIAL THE
LINEAR COPY FUNCTIONS OF BOTH THE CONSTRUCTION & THE GROUPS
AREA ARE EXPLAINED. FIRST LET'S CREATE A SHAPE TO COPY.
<end>
PRESS "1" FOR THE MENU.
FROM THE COPY SECTION OF THE MENU SELECT "LINEAR CC" FOR
LINEAR COPY WITH A COMPLETELY CONTAINED WINDOW.
<end>
LOOK AT THE FIRST THREE SUBMENUS OF THIS FUNCTION FROM LEFT
TO RIGHT. "QTY" (QUANTITY), "SPACE" (SPACE BETWEEN ANY TWO
COPIES) & "UP TO" THE DISTANCE COVERED BY ALL COPIES. TWO OF
THESE THREE VARIABLES MUST BE USED TO CREATE LINEAR COPIES.
TO CREATE A QTY OF 5 COPIES WITH THE Spacing OF 2.0
(IN THIS CASE) METERS, THE STEPS ARE AS FOLLOWS:
<end>
FIRST IDENTIFY THE OBJECT BY DRAWING A WINDOW AROUND IT.
NOTICE THAT THE OPTION C.C. (COMPLETELY CONTAINED) IS THE
DEFAULT TYPE OF WINDOW.  LET'S IDENTIFY THE SHAPE BY
COMPLETELY CONTAINING IT IN A WINDOW.
<end>
NEXT SELECT "QTY" AND ENTER FIVE (WITHOUT A DECIMAL POINT).
AND PRESS THE ENTER KEY.
<end>
TO SET THE SPACE BETWEEN COPIES CLICK TWICE & PICK TWO
POINTS. THE DISTANCE AND THE DIRECTION BETWEEN THESE TWO
POINTS ARE ASSIGNED TO ALL 5 COPIES.  SAY THE SPACE BETWEEN
EACH COPY IS 2.0 METERS.  PICK THE FIRST BY CLICKING THE
CURSOR AND FOR THE SECOND POINT PRESS "F10" & ENTER A HORI-
ZONTAL DISTANCE OF 2.0 .  ALL 5 COPIES ARE THUS CREATED.
<end>
TO ILLUSTRATE ANOTHER METHOD TO USE LINEAR COPY FUNCTIONS OF
THE CONSTRUCTION AREA, A NEW SHAPE HAS BEEN GENERATED.  ALSO
A LINE THAT IS 12 METERS LONG IS DRAWN FOR VISUAL REFERENCE.
ONCE AGAIN SELECT "LINEAR CC" FROM THE CONSTRUCTION MENU.
<end>
TO ILLUSTRATE THE USE OF THE VARIABLES "SPACE" AND "UP TO"
FIRST IDENTIFY THE SHAPE WITH A CC WINDOW.
<end>
NOTICE THAT THE
GREEN LINE IS NOT COMPLETELY CONTAINED IN THE WINDOW AND
THEREFORE IS NOT COPIED.
SELECT "SPACE" & SPECIFY 2.0 METERS.  THE DISTANCE OF
2.0 METERS IS ENTERED MANUALLY BY FIRST PRESSING THE "F10"
KEY AND THEN TYPING 2.0 FOR THE HORIZONTAL MOVEMENT OF THE
CURSOR AND ZERO FOR ITS VERTICAL MOVEMENT.
<end>
NOW SELECT "UP TO" AND WITH THE HOOKS GRAB THE END OF THE
GREEN LINE.  SINCE THE 12.0 METER LENGTH OF THE LINE IS
DIVISIBLE BY 2.0 METER SPACING, A QUANTITY OF SEVEN COPIES
ARE PLACED ALONG THE LENGTH OF THE GREEN LINE.
PRESS "9" FOR THE HOOKS THEN SELECT THE SUBMENU OPTION
"UP TO" & GRAB THE RIGHT END OF THE GREEN LINE WITH HOOKS.
<end>
THIS IS A VERY GOOD METHOD OF DIVIDING A DISTANCE INTO EQUAL
SPACES.  HERE IS ANOTHER EXAMPLE:
<end>
TO DIVIDE THIS RED LINE INTO 12 EQUAL SPACES, DRAW A LINE AT
ONE END TO SERVE AS A VISUAL MARKER THEN MAKE 13 COPIES OF
THAT LINE ALONG THE LENGTH OF THE RED LINE.  NOTICE THAT
SINCE 13 VISUAL MARKERS DIVIDE A DISTANCE INTO 12 EQUAL
SPACES IT CAN BE CONCLUDED THAT ONE MORE DIVIDER MUST BE
SPECIFIED THAN THE NUMBER OF DIVISIONS.HERE IS HOW IT WORKS.
<end>
FIRST A VISUAL MARKER OR DIVIDER. NOTICE THAT HOOKS ARE
ARE DEACTIVATED IMMEDIATELY AFTER USE.
THIS IS A VERY GOOD HABIT TO DEVELOP.
<end>
LET US MAKE 13 COPIES OF THE YELLOW LINE ALONG THE LENGTH OF
THE RED LINE USING "LINEAR CC".
<end>
SELECT "QTY" AND SPECIFY 13.
<end>
PICK UP THE YELLOW LINE.
<end>
SELECT "UP TO".
<end>
AND SPECIFY THE OTHER END OF THE RED LINE.  IN FACT WE ARE
SAYING TO THE SOFTWARE TO MAKE 13 COPIES OF THE YELLOW LINE
STARTING FROM ONE END OF THE RED LINE & ENDING AT OTHER END.
<end>
NOW HERE IS THE SAME PRINCIPLE APPLIED TO A LINE THAT IS
AT AN ANGLE.  THE PROCEDURE IS THE SAME.
<end>
START BY SELECTING THE "LINEAR CC" FUNCTION FROM THE MENU.
<end>
OF ALL THE VARIABLES ON THE SUBMENU OF THE LINEAR FUNCTION
ALWAYS SPECIFY QUANTITY (QTY) FIRST. THIS IS IMPORTANT.

IF THE SOFTWARE COULD HEAR US TALK WE WOULD BE SAYING TO IT:

MAKE QUANTITY OF 13 COPIES ......
<end>
OF THIS LINE.......
<end>
FROM HERE .......
<end>
UP TO .......
<end>
HERE .........
<end>
THE FUNCTION LINEAR COPY IS ALSO AVAILABLE IN THE GROUPS
AREA AND IT IS APPLIED IN MUCH THE SAME WAY TO THE GROUPS.
WE NEED A GROUP OR TWO TO PRACTICE WITH. SO LET'S GROUP
SOME OF THE EXISTING GEOMETRY AND ERASE THE REST.
<end>
PRESS "5" TO GO TO THE GROUPS AREA.
<end>
SELECT "LINEAR SNG" TO COPY A SINGLE GROUP LINEARLY.
<end>
THE SUBMENU OF THIS FUNCTION HAS AN "UNDO" OPTION TO ERASE
THE RESULTS OF THE LAST LINEAR COPY ATTEMPT.  THE "ZAXIS" IS
USED TO SPECIFY A Z-AXIS VALUE WHEN CREATING 3D DRAWINGS.
"QTY" WORKS LIKE AS IT DID IN THE CONSTRUCTION AREA. HOWEVER
THE OPTION "SPACE" IS AUTOMATICALLY ASSUMED.  HERE IS HOW:
LET'S SAY WE WANT 5 COPIES OF THIS GROUP 2.0 METERS APART.
<end>
AS IF WE COULD TALK TO THE COMPUTER ..........
MAKE 5 COPIES .........
<end>
OF THIS GROUP .........
<end>
AND PICK IT UP BY THIS POINT .......
<end>
THEN PUT 2.0 METERS BETWEEN EACH COPY (PRESS "F10") .....
<end>
THE EQUIVALENT OF THE OPTION "UP TO" IS AUTOMATICALLY
ASSUMED BY THE SOFTWARE IN THE SAME FASHION AS THE OPTION
"SPACE" IS ASSUMED AS YOU GO THROUGH THE STEPS OF THIS
FUNCTION.
<end>
HERE IS A VERY PRACTICAL APPLICATION OF THE LINEAR COPY
FUNCTIONS OF BOTH THE CONSTRUCTION AND THE GROUPS AREA.
FIRST LET US CLEAN THE SCREEN USING "GRPS/CONTS" FUNCTION.
<end>
WITH THIS FUNCTION YOU MAY ERASE THE ENTIRE CONTENTS OF
THE CONSTRUCTION ARE   OR   THE GROUPS AREA   OR   BOTH.
\
***********************  WARNING ***************************
THE EFFECTS OF THIS FUNCTION CAN NOT BE REVERSED OR UNDONE.
<end>
PRESS ANY KEY AFTER READING THE WARNING ON THE DATA LINE.
<end>
PRESS ANY KEY AFTER READING THE WARNING ON THE DATA LINE.
<end>
ERASE THE ENTIRE CONTENTS OF THE CONSTRUCTION & GROUPS AREAS
BY SELECTING "DO IT".  IF YOU CHANGE YOUR MIND PRESS "."
OTHERWISE SELECT "DO IT".
<end>
NOW LET US CHANGE THE RESOLUTION TO 1/16" AND THE UNIT OF
MEASUREMENT TO "FEETD" (FEET DECIMAL DISPLAY).
YOU MAY REMEMBER FROM PREVIOUS TUTORIALS THAT THE RESOLUTION
IS THE SMALLEST MOVEMENT OF THE CURSOR IF YOU ARE NOT
FAMILIAR WITH THIS CONCEPT STUDY TUTORIAL 052 AND READ THE
SECTION TITLED "RESOLUTION" IN THE ON-LINE HELP/MANUAL.
<end>
LET US DRAW THE ELEVATION OF A 3'X8.333' (3'-0"X8'-4") DOOR.
<end>
LET US LEARN A SHORTCUT. BUT FIRST RECREATE THE OUTLINE OF
THE DOOR AND THE FIRST 2 SQUARES AS FOLLOWS:
<end>
SELECT "LINEAR CC" AND DRAW A WINDOW AROUND THE 2 SQUARES.
<end>
WITHOUT SELECTING ANY SUBMENU OPTIONS PICK UP THE 2 SQUARES
BY ANY POINT.
<end>
PRESS "F10" AND SPECIFY 1.333 FEET VERTICALLY.
<end>
USING HOOKS SELECT THE TOP OF THE DOOR (SPECIFYING THE POINT
UP TO WHICH THE SQUARE ARE TO BE COPIED).
<end>
AS YOU SAW IF THE OPTIONS "SPACE" & "UP TO" ARE NOT SELECTED
THE SOFTWARE AUTOMATICALLY ASSUMES THEM IN THAT ORDER.  HERE
IS THE SAME EXAMPLE ONE MORE TIME EXPLAINED STEP BY STEP.
<end>
COPY THESE TWO SQUARES ........
<end>
PICK THEM UP BY THIS POINT .........
<end>
NOTICE THAT THE SUBMENU OPTION "SPACE" IS STILL NOT SELECTED.
<end>
ASSIGN A DISTANCE OF 1.333 FEET VERTICALLY....... use "F10"
<end>
LOOK AT THE SUBMENU AND NOTICE THAT THE OPTION "SPACE" HAS
BEEN AUTOMATICALLY SELECTED.

AND PUT AS MANY OF THEM AS WILL FIT UP TO THIS POINT.......
<end>
OK, NOW LET US GROUP ONE OF THE DOORS AND ERASE THE OTHER.
<end>
DOORS BELONG TO LEVEL 004 SO SELECT THE LEVEL ICON ABOVE
AND TYPE 4 AND PRESS ENTER.
<end>
NOW LET US CREATE A SIMPLE EXTERIOR ELEVATION.
<end>
THE OUTLINE OF THIS ELEVATION BELONGS TO LEVEL 011.
<end>
LET US PLACE THE DOOR 2 FEET TO THE RIGHT OF THE LEFT CORNER
OF THE ELEVATION.
<end>
SELECT "MOVE SNG" TO MOVE A SINGLE GROUP.
<end>
MOVE THIS DOOR .....
<end>
(PRESS "9" TO TURN ON THE HOOKS)

PICK IT UP BY THIS POINT.....
<end>
MAKE THE COORDINATES OF THIS POINT ZERO (X=0,Y=0).....

THIS IS DONE BY HOLDING THE CURSOR OVER THE LOWER LEFT
CORNER OF THE ELEVATION AND PRESSING "0".
<end>
TURN OFF THE HOOKS....
<end>
AND PLACE THE DOOR 2' TO THE RIGHT ......

PRESS "F10" AND TYPE 2.0 HORIZONTALLY TO
<end>
THE DOOR IS PLACED 2'-0" TO THE RIGHT OF THE CORNER SINCE
EARLIER WE SET THE COORDINATES OF THE CORNER TO ZERO.

LET US PUT THE MIRROR IMAGE OF THE DOOR ON THE OTHER SIDE.
<end>
FROM THE MENU'S COPY FUNCTIONS SELECT "RANDOM SNG" TO
RANDOMLY COPY A SINGLE GROUP (THE DOOR).
<end>
COPY THIS DOOR ......
THEN FIRST TURN ON THE HOOKS ......
<end>
PICK UP A COPY OF THE DOOR BY THIS POINT.......
<end>
MIRROR THE COPY ABOUT THE VERTICAL AXIS (SELECT OPTION
"MIR Y" FROM THE SUBMENU......
<end>
AND PLACE THE COPY HERE .......
<end>
PRESS "." SINCE WE DO NOT WANT ANYMORE COPIES OF THE SAME
DOOR USING THE RANDOM COPY METHOD.
<end>
LET US PUT 5 MORE DOORS BETWEEN THESE TWO EQUALLY SPACED
APART.  TO DO SO WE MUST DIVIDE THE DISTANCE BETWEEN THE
LOWER RIGHT CORNERS OF THE TWO DOORS INTO 6 EQUAL SPACES.
AS USUAL WE NEED 1 MORE DIVIDER THAN THE NUMBER OF DIVI-
SIONS.  THAT MEANS WE NEED 7 LINE SEGMENTS BETWEEN THE
TWO DOORS.
<end>
THE INTERSECTIONS OF THE CYAN LINES WITH THE BASE OF THE
ELEVATION MARK THE LOCATION OF ADDITIONAL COPIES OF THE DOOR
AND THE DISTANCE BETWEEN ANY TWO CONSECUTIVE INTERSECTIONS
IS THE DISTANCE BETWEEN ALL COPIES OF THE DOOR.
<end>
LET US USE "LINEAR SNG" TO COPY THE DOORS GRABBING THEM BY
THEIR LOWER RIGHT CORNER.
<end>
MAKE 5 COPIES.......
<end>
OF THIS GROUP.....
<end>
PICKED UP BY THIS POINT......
<end>
WITH THIS SPACING BETWEEN ALL 5 COPIES......
<end>
NOTICE THAT THE SOFTWARE TAKES INTO ACCOUNT THE ORIGINAL
DOOR AS ONE OF THE COPIES HENCE CREATING 4 NEW DOORS.
<end>
SELECT "UNDO" TO ERASE THE LATEST COPIES.
<end>
LET'S SPECIFY A QUANTITY OF 6 COPIES THIS TIME .......
<end>
OF THIS GROUP.......
<end>
PICKED UP BY THIS POINT.
<end>
WITH THIS SPACING BETWEEN THE 6 COPIES.......
<end>
SINCE EACH DOOR IN THIS EXAMPLE HAS BEEN A COPY OF THE
ORIGINAL DOOR (REGARDLESS OF THE METHOD BY WHICH DOORS WERE
COPIED) THEIR QUANTITY CAN BE AUTOMATICALLY COUNTED AND
MUCH LESS MEMORY IS USED UP AS OPPOSED TO THE CONDITION WERE
EACH DOOR WAS SEPARATELY CREATED.  LET'S SEE HOW MANY DOORS
ARE ON THE SCREEN.  SELECT "INFO GROUP".
<end>
CLICK ON A DOOR AND READ THE STATUS LINE.
<end>
AS YOU CAN SEE ALL COPIES OF THIS DOOR ARE ON LEVEL 4 AND
THERE ARE 7 OF THEM ON THE SCREEN.
CAUTION: IF A DOOR IS EXPLODED (TRANSFERRED TO CONSTRUCTION
AREA) AND THEN GROUPED AGAIN, IT MAY LOOK THE SAME BUT IT
WOULD NOT BE ONE THE ORIGINAL DOORS.  THEREFORE DO NOT
EXPLODE GROUPS UNLESS TO CHANGE THEIR PHYSICAL APPEARANCE.
<end>
WE MAY NOW ERASE THE CYAN LINES.
<end>
