**** Welcome to the CADKEY CADL Utilities Diskette **** Version Date 6/22/89 This diskette contains several useful construction utilities, examples of applications, and outlines of command usage. Each utility and application program is described in the following text. Each descrip- tion contains an outline of the task which is performed, as well as a set of instructions relating to the operation of the program. The purpose of CADL is to allow you to do things with the data base, graphics, and construction capabilities available in CADKEY 3. CADL allows you to use all these capabilities in ways that CADKEY 3 was never designed to do itself. One of the programs on this diskette of miscellaneous utilities demonstrates how to communicate bidirectionally between a CADL program and macros, so that the macros function as if they were subroutines of the CADL program. See STARTEX1.TXT for this extremely useful tool. You can use CADKEY 3 to fill gaps in CADL or to speed things up. You can also use EXEC to leave CADKEY 3 temporarily, and go to DOS if you need additional capabilities not available in CADKEY 3 or in CADL. If you need even more computing power, you can use EXEC to go to specialized routines in Fortran, Basic or C that you may have written for your own needs. Thanks to the AUTOSWAP program, you can use routines as large as 500K and even larger. ************************************************ You should note, that this is a utility disk which may be used as a tool for performing tasks or as reference for generating additional pro- grams. You should also note that the programs contained in these disks are from various sources and that support for these programs is limited. ************************************************* ------------------------------------------------- | | | WARNING!! | | | ------------------------------------------------- Before running these programs, run CONFIG. In the programming options (Option 6), 1. Set the number of CADL labels to 120 or more. 2. Set the number of register variables to 180 or more. If you run very long CADL programs, set the number of CADL labels and register variables even higher. SHAPES and UTILITY are designed to run ONLY in a single viewport configuration. Running them in multiple viewports will cause strange results and possible system crashes. *************************************************** * This diskette includes some text files that are * * macros. You should load them into the macro * * library using the TXT-IN command. * *************************************************** We plan to update many of these CADL programs during the year. You will find the updates available through your CADKEY dealer, in 3-D WORLD or in the CADKEY Forum on the CompuServe Information Service. You can make a CADL program run much faster if you compile it before you use it. CADKEY will publish an updated CADL Programmer's Guide in the Fall 1989 which will include program hints and examples. Several of the programs contained on this disk, have associated files. Some of these associated files are in the form of executable programs, while others are data files accessed or created by the program. These files, similiar to the CADL programs, must be copied into there appro- priate directories if the main programs are to run correctly. The file scheme for these programs are shown in the following outline. File type Description Directory --------- ----------- --------- xxx.CDL CADL pgms \cadkey\cdl xxx.COM Executable pgms \cadkey xxx.EXE ------------------------------------------------- | | | ADDITIONAL WARNING!! | | | ------------------------------------------------- Some of the CADL and executable programs use scratch or data files that are "hard coded" to access the \cadkey\cdl\ directory. If errors ocurr in these programs, you should check to see if these programs/files are in the proper location and/or directories. Also, please note that the executable programs require at least 28K in order to run correctly. It is suggested that the DOS memory be set to 50K in order to allow these programs to operate. ------------------------------------------------------------------- This diskette also contains a CADL program called "utility" which will display a menu of user selectable CADL programs found on the disk. NOTE: You can run most, but NOT ALL, of the programs on this diskette through "utility." Once the files have been copied to their appropriate directories, this program may be accessed through the FILES - CADL - EXECUTE menu in CADKEY. Executing the program "utility" will display of menu of selectable CADL utility programs. Selecting one of the choices with the cursor will activate the particular program. Also contained as a menu option, are two additional choices; Help and Next page. By indicating "HELP," a description of the programs dis- played on the current page are shown. By selecting the option "Next page", the present list of program is erased and the next available page of CADL programs is displayed for selection. You can also imbed a CADL program in a macro and attach the macro to a keystroke or to the menu structure. -------------------------------------------------------------------------------- 2dxform.cdl -------------------------------------------------------------------------------- Task: This program performs a transformation (copy) that combines the translation and rotation of one or more entities in x and y coordinates. The program prompts you to enter a base point and an orientation of the entities. It then prompts you to indicate a new position for the base point and a new orientation. How to use: FILES - CADL - EXECUTE, enter: 2dxform You can specify the level on which you want the new geometry to be created. The program displays a menu allowing you to select entities individually ("SINGLE") or in groups ("CHAIN" or "WINDOW"). Choose the desired option, and select the entities to be translated and rotated into a new x,y position. Indicate the entity's old base point and old main direction point (orientation). Indicate the new base point and the new main direction point into which the entity is to be copied. After the entity has been copied into its new x,y position, you can continue to place it into other new positions by specifying other new base points and new orientations. To stop the program and return to the CADL menu, press <ESC> or F10. Before leaving 2dxform, the program asks you if you want to delete the original entities that you selected. It is not possible to tilt entities using 2dxform. -------------------------------------------------------------------------------- 3dxform.cdl -------------------------------------------------------------------------------- Task: This program performs a transformation (copy) that combines the translation and rotation of one or more entities in x, y and z coordinates. The program prompts you to enter a base point and a primary and secondary orientation of the entities. It then prompts you to indicate a new position for the base point and new primary and secondary orientations. It is possible to tilt entities using 3dxform. How to use: FILES - CADL - EXECUTE, enter: 3dxform You can specify the level on which you want the new geometry to be created. The program displays a menu allowing you to select entities individually ("SINGLE") or in groups ("CHAIN" or "WINDOW"). Choose the desired option and select the entities to be translated and rotated into a new x,y,z position. Indicate the entity's old base point, old main direction point (primary orientation), and old secondary direction point (secondary orientation). Indicate the entity's new base point, new main direction point, and new secondary direction point. After the entity has been copied into its new x,y,z position, you can continue to place it into other new positions by specifying other new base points, new primary orientations, and new secondary orientations. To stop the program and return to the CADL menu, press <ESC> or F10. Before leaving 3dxform, the program asks you if you want to delete the original entity or set of entities that you selected. -------------------------------------------------------------------------------- 3drot.cdl -------------------------------------------------------------------------------- Task: This program allows you to copy and rotate an entity or a set of entities about two positions which represent a rotation axis. This utility may be used in any view. The user has the option of using single, chain, or window selection to specify the entities to be copied. How to use: FILES - CADL - EXECUTE, enter: 3drot You can specify the level on which you want the entities to be constructed. The next step involves selecting the entities which will be rotated about an axis. The selection menu will allow you to choose between SINGLE, CHAIN, or WINDOW. Select the desired option and indicate the entities to transform. Using the Position Menu, indicate the two positions which will represent the rotation axis. After indicating the axis, enter the angle of rotation to be applied and the number of copies to be created. The entities selected will be copied based on the rotation angle and number of copies specified. After the construction, you have the option of deleting the original entities which were rotated. -------------------------------------------------------------------------------- gmupdate.cdl -------------------------------------------------------------------------------- Task: This program redefines points, lines and arcs by updating the data in the part file's data base. If the entity selected is a point, the system displays a set of menus that allow you to update the view or world coordinates of the point. If the entity selected is a line, the system displays a set of menus that allow you to update the view or world coordinates of the end points of the line. If the entity selected is an arc, the system displays a set of menus that allow you to update the view or world coordinates of the center of the arc, as well as the arc's start and end angles and its radius. In each case the entity is recreated using the new data. How to use: FILES - CADL - EXECUTE, enter: gmupdate Select the entity to update. -------------------------------------------------------------------------------- ptsurf.cdl -------------------------------------------------------------------------------- Task: This program projects points onto a three-sided polygonal surface in the direction of the current view. How to use: FILES - CADL - EXECUTE, enter: ptsurf Enter the level on which you want to store the new points. Indicate twice the point to project. The first pick selects the point. The second pick selects the polygon to which the point is to be projected. ------------------------------------------------------------------------------- 2ptfil.cdl ------------------------------------------------------------------------------- Task: This program creates a fillet between two points with a given radius. It creates the arc counterclockwise (CCW) from the first point selected to the second point. Notes: Points must be at the same depth in the view in which you select the first point, or with respect to an active construction plane. The distance between the points must not be larger than twice the radius of the fillet. How to use: FILES - CADL - EXECUTE, enter: 2ptfil Enter the fillet's radius. Indicate the first and second points. -------------------------------------------------------------------------------- twoptsvw.cdl -------------------------------------------------------------------------------- Task: This program creates a line-of-sight view along two given points. The positive side of the view is the side of the first point that you select. How to use: FILES - CADL - EXECUTE, enter: twoptsvw Indicate the first and second points. A new view is created and added to the data base. -------------------------------------------------------------------------------- lnptang.cdl -------------------------------------------------------------------------------- Task: This program creates a line at a user-specified angle to an existing line which passes through a selected point. Note: This program works in any view, and the line constructed exists on the plane determined by the point and line selected. How to use: FILES - CADL - EXECUTE, enter: lnptang Indicate the a line to serve as the base line. Entering a <return> designates the x-axis as the base line. Indicate the base position. Enter the angle from the base line. -------------------------------------------------------------------------------- lnpartan.cdl -------------------------------------------------------------------------------- Task: This program creates a line tangent to an arc or circle and parallel to another existing line. Note: This program works in any view. Restriction: The arc/circle (with which the new line will be tangent) and the line (with which the new line will be parallel) must be coplanar. How to use: FILES - CADL - EXECUTE, enter: lnpartan Indicate the line to which the new line will be parallel. Indicate the arc or circle to which the new line will be tangent. After the line appears, you can continue selecting additional arcs or circles to create additional lines. -------------------------------------------------------------------------------- lnpptan.cdl -------------------------------------------------------------------------------- Task: This program creates a line tangent to an arc or circle and perpendicular to another line. Note: This program works in any view. Restriction: The arc/circle (with which the new line will be tangent) and the line (with which the new line will be perpendicular) must be coplanar. How to use: FILES - CADL - EXECUTE, enter: lnpptan Indicate the line to which the new line will be perpendicular. Indicate the arc or circle to which the new line will be tangent. After the line appears, you can continue selecting additional arcs or circles to create additional lines. -------------------------------------------------------------------------------- cincispl.cdl -------------------------------------------------------------------------------- Task: This program creates three types of parabolic splines (using a quadratic equation as opposed to a cubic equation) as well as a linear representation. The program stores these parabolic splines inside the CADKEY spline entity. CADKEY 3 uses this new entity as if it were a normal spline. Note: This program gives you the following options: CINCI FORWARD BLEND LINEAR How to use: FILES - CADL - EXECUTE, enter: cincispl Select the spline interpolation type. Using the position menu, indicate the points of the spline. The spline will then be constructed. Use <ESC> to exit the program, F10 to backup to the interpolation menu, or select additional positions to create another spline. -------------------------------------------------------------------------------- cirlnend.cdl -------------------------------------------------------------------------------- Task: This program will a circle at the endpoints of an existing line. The arcs will be constructed perpendicular to the vector formed by the existing line. The arcs will represent a cylinder with the line as the axis. How to use: FILES - CADL - EXECUTE, enter: cirlnend Select the desired axis line. Enter the radius of the arcs to be constructed. The arcs will then be constructed at both ends of the axis line, and you can continue to select additional lines. -------------------------------------------------------------------------------- lntanang.cdl -------------------------------------------------------------------------------- Task: This program creates a line tangent to an arc, at a given angle from a user-specified base line. The line and arc must be coplanar. How to use: FILES - CADL - EXECUTE, enter: lntanang Indicate the a line to serve as the base line. Entering a <return> designates the x-axis as the baseline. Enter the angle from the base line. Indicate the arc or circle to which the new line will be tangent. -------------------------------------------------------------------------------- cylint.cdl -------------------------------------------------------------------------------- Task: This program will construct a spline which represents the intersection of two cylinders. Note: Each cylinder for this program must be represented by two circles. All together this program requests that four circles be selected. How to use: FILES - CADL - EXECUTE, enter: cylint Cursor-indicate the first circle representing the first cylinder. Indicate the second circle representing the first cylinder. Indicate the first circle representing the second cylinder. Indicate the second circle representing the second cylinder. The program will transfer control to an executable program in the DOS shell. When the operation is complete, press <return> to re-enter CADKEY, and the intersection(s) will be created. -------------------------------------------------------------------------------- splpar.cdl -------------------------------------------------------------------------------- Task: This program creates a 2-D or 3-D cubic spline offset from an existing spline. Notes: This program mathematically offsets the nodes (or knot points) of a new spline from the nodes of the original spline. The new spline's offset is mathematically correct only at the nodes. The new spline itself is not necessarily parallel to the original spline. The number of nodes in the original spline determines how closely parallel the new offset spline will be to the original spline. The more nodes there are in the original spline, the more truly parallel the offset spline will be. SPLPAR.CDL works correctly for 2-D splines and for 3-D splines in which at least one of the coordinates of every node (x, y or z) is constant in a single plane. SPLPAR.CDL does not work for 3-D splines in which all three coordinates of a node (x, y and z) can be on different planes. How to use: FILES - CADL - EXECUTE, enter: splpar Select the spline that you want to offset. Enter the desired offset. The program identifies the type of spline that you have selected. Credit: SPLPAR.CDL was designed and written by Haig Saadetian of Carr-Sawyer Systems, Inc., Weston, Ontario, Canada. -------------------------------------------------------------------------------- postrim.cdl -------------------------------------------------------------------------------- Task: This program will allow you to trim or extend an existing line to an indicated position. How to use: FILES - CADL - EXECUTE, enter: postrim Select the line to trim or extend. Using the position menu, indicate a position to which you want to trim or extend the line. The line will be reconstructed to the new position. -------------------------------------------------------------------------------- ptvector.cdl -------------------------------------------------------------------------------- Task: This program allows you to create a point based on a selected vector defined by a line and a direction, and a specified distance. This function can also be used as a more flexible version of creating a point along a line. Note: This program is view independant. How to use: FILES - CADL - EXECUTE, enter: ptvector Indicate a line which will represent the 3D vector to be used for the point construction. Indicate a position to designate the direction where the point will be created. Indicate a base point or position for the transformation. Enter the delta distance from the base point. A point will be created at the specified distance from the base point using the 3D vector for direction. -------------------------------------------------------------------------------- cline.txt -------------------------------------------------------------------------------- Task: This program is a macro to insert a centerline into an arc or a circle. How to use: FILES - MACROS - LIBRARY - TXT-IN, enter: cline FILES - MACROS - LIBRARY - LST/EXE, select: cline or: CTRL-E, enter: cline Select an arc or circle for inserting a centerline. The centerline is proportioned to the size of the arc or circle. You can continue select arcs or circles, one at a time, until you stop the macro. -------------------------------------------------------------------------------- startex1.txt -------------------------------------------------------------------------------- Task: This macro sets system parameters (level, color, view, mask, pen, line type, line width, text, note height, aspect, angle, dimension height, dimension scale) according to a user-selected example entity. This macro executes its task in association with the following files: ex1.txt dimchg.txt dimht.txt dimscl.txt endex1.txt exampl1.cdl This set of programs shows a technique of how to communicate bidirectionally between CADL programs and macros. In essence, this demonstrates CADL's ability to use macros as if they were subroutines -- an extremely useful tool! How to use: FILES - MACROS - LIBRARY - TXT-IN, enter: startex1 FILES - MACROS - LIBRARY - LST/EXE, select: startex1 or: CTRL-E, enter: startex1 Select the example entity. -------------------------------------------------------------------------------- tbox.cdl -------------------------------------------------------------------------------- Task: This program allows you to write text into pre-defined locations in a title block. To do this, you create a template file that defines the field name, text size, text height, aspect ratio, font, and pen number for each one of the fields in the title block. The template file is an ASCII file stored in the CADKEY's main directory. This program displays a menu that allows you to select: 1. Create Template: Allows you to define the field positions, widths, and text attributes. 2. Append Field: Allows you to append new fields to a template file. 3. Modify Field: Allows you to modify parameters in a single field of a template file. 4. Write Field: Allows you to write a single field to the title block. 5. Write Template: Writes the entire title block using the default text in each one of the fields of the template file. An efficient way to use this program is to edit the default text fields in the template file, and then to write the entire title block using the Write Template option. How to use: FILES - CADL - EXECUTE, enter: tbox -------------------------------------------------------------------------------- winmgr.cdl -------------------------------------------------------------------------------- Task: This program allows you to create and manage (add or delete) additional view-dependent windows of a part in CADKEY 3 beyond the capability of two windows that you can currently create using ALT-W and ALT-B. Note: This program, along with its accompanying macro PICT1.TXT, is particularly useful for large part files. It eliminates the need to change view, autoscale, and window to create a new window of a section of the part. The macro PICT1.TXT can be used as an immediate mode command. To increase speed, bind PICT1.TXT to a keystroke. How to use: FILES - CADL - EXECUTE, enter: winmgr Select the window-manager option: ADD DELETE INITIAL (Initialize) Suggested procedure for use: Step 1. Select INITIAL to clear the stack of windows. Step 2. Select ADD to create and store new windows. Step 3. To use the windows, use the immediate- mode command CTRL-E, and enter PICT1. Then, enter the desired window number. Credit: WINMGR.CDL and PICT1.TXT were designed and written by Robert Bean of Baystate Technologies, Worcester, Massachusetts. -------------------------------------------------------------------------------- sc.cdl -------------------------------------------------------------------------------- Task: This program sets all the CADKEY view ports to the same scale, and it centers the part displayed in each view port. How to use: FILES - CADL - EXECUTE, enter: sc Enter the scale factor for the view ports. -------------------------------------------------------------------------------- tubecl.cdl -------------------------------------------------------------------------------- Task: This program allows you to define the 3-D centerline of a tube through a set of user-specified control points and bend radii. You can choose to specify a bend radius that will be common to all bends in the tube, or to specify each bend radius individually. Note: You can indicate the control points on the screen with the position menu and cursor, or by reading them from an ASCII file. If all the bends have a common radius, the format of the file is: X1, Y1, Z1 X2, Y2, Z2 Xn, Yn, Zn If the bends have different radii, the file format is: X1, Y1, Z1 X2, Y2, Z2 R1, X3, Y3, Z3 R2, X4, Y4, Z4 R(n-2), Xn, Yn, Zn The centerline proceeds in a linear progression from its starting point to its ending point. This means that the end-point of any entity (line or arc) in the centerline coincides with the start-point of the following entity, except for the last entity. TUBECL.CDL was originally donated as free-of-charge shareware to the CADKEY Forum on the CompuServe (R) Information Service. How to use: FILES - CADL - EXECUTE, enter: tubecl -------------------------------------------------------------------------------- cstube.cdl -------------------------------------------------------------------------------- Task: This program creates a CADL file that serves as input to CADKEY SOLIDS which creates a solid representation of the tube. Note: The centerline created by TUBECL.CDL serves as the input to CSTUBE.CDL. The chain of the centerline's lines and arcs that you specify in CSTUBE must start at the same point and proceed in the same sequence as it was created by TUBECL. CSTUBE.CDL was originally donated as free-of-charge shareware to the CADKEY Forum on the CompuServe (R) Information Service. How to use: FILES - CADL - EXECUTE, enter: cstube -------------------------------------------------------------------------------- tubedge.cdl -------------------------------------------------------------------------------- Task: This program generates an edge view of a tube. Note: Creating this edge view is quite complex, especially for inside bends. The centerline created by TUBECL.CDL serves as the input to TUBEDGE.CDL. The chain of the centerline's lines and arcs that you specify in TUBEDGE must start at the same point and proceed in the same sequence as it was created by TUBECL. WARNING: STORE YOUR PART FILE BEFORE RUNNING TUBEDGE. TUBEDGE is still in development and may contain errors. TUBEDGE.CDL was originally donated as free-of-charge shareware to the CADKEY Forum on the CompuServe (R) Information Service. How to use: FILES - CADL - EXECUTE, enter: tubedge -------------------------------------------------------------------------------- shapes.cdl -------------------------------------------------------------------------------- Task: SHAPES is a group of CADL programs that allows you to create shapes parametrically in a CADKEY part file. Notes: Icons help you to select the specific CADL program that will generate the desired shape. Icons also display the variables (dimensions) that you must supply to the CADL program to create the shape. SHAPES was originally donated as free-of-charge shareware to the CADKEY Forum on the CompuServe (R) Information Service. Introduction: SHAPES is a framework that you may take as an example of how to integrate CADL programs into a single structure. You may also adapt SHAPES to their own needs. All of the shapes currently available in SHAPES are two-dimensional. However, SHAPES can easily be extended into three dimensions to create such shapes as bolts, nuts, clamps, etc. SHAPES is essentially composed of a main file, SHAPES.CDL, and two subroutine files, SH_SCRN.CDL and RESTORE.CDL, plus a variety of CADL icon files which define the shapes that they represent. SHAPES provides two levels of icons for creating each geometric shape, an icon for the SHAPES menu and an icon that identifies the parameters that you must specify in order to create the shape in a part file. SHAPES.CDL displays icons on the screen and calls a specific, shape-defining CADL file when you select a particular icon with the cursor. The CADL file that corresponds to the selected icon will actually create the shape once you have entered the necessary parameters. Example: If you are designing a part in CADKEY 3 and need to create an oval, SHAPES can help you. Using the command sequence, FILES, CADL, EXECUTE, the screen prompts you for a file name. Enter SHAPES. The screen displays the SHAPES icon menu. One of the icons that you see is an oval. Select this icon with the cursor. The screen displays that icon by itself with labels identifying the dimensions that you must specify to enter the geometry represented by that icon into your part file. The bottom of the screen also displays a prompt line referring to the first dimension's name and giving a default value for that dimension. Enter the data required for each dimension: length, width, radius and angle. The screen now prompts you for the location in which you want the oval placed in your part file. After you enter the required data, CADKEY creates the oval in the location that you specified. You may choose to display the oval's center lines and to enter that same geometry in another location. If you prefer to enter a different shape, use BACKUP (F10) or <ESC> to exit from the CADL file for defining an oval. The screen displays the icon menu again. You can select another icon, activating the CADL file that it represents to create and insert a new shape into your part file, such as a rounded slot, a radial slot, a sharp-cornered-rounded slot, or an open-ended slot. Or, you may use <ESC> to exit SHAPES and return to your part file. This section of the README35.DOC file focuses on two questions: 1. How does SHAPES work? 2. How do I use SHAPES? How it works: SHAPES.CDL sets the initial variables for the icons to be displayed, then displays the icon menu by calling the subroutine SHSCREEN.CDL. The icons that are displayed represent shape-defining CADL files which SH_SCRN.CDL calls as subroutines. You can customize SHAPES by adding your own, specific, geometry-defining CADL file to the list of subroutines in SH_SCRN.CDL, and by identifying in SHAPES.CDL the menu position in which you want the icon to be displayed. RESTORE.CDL restores the original variables defined by SHAPES.CDL. SHAPES' current icon menu is a matrix containing 16 squares. (The number of squares in the menu can be modified as needed. The procedure for modifying the menu will be described in the next paragraph.) The position of each square is identified by the column and row in which it is located. The columns are numbered from left to right: 1, 2, 3, 4. The rows are numbered from bottom to top: 1, 2, 3, 4. The name of each square in the matrix is a combination of that square's column number and row number, beginning with "pos11" in the lower left corner, as illustrated below: --------------------------------- | | | | | | pos14 | pos24 | pos34 | pos44 | | | | | | |-------------------------------| | | | | | | pos13 | pos23 | pos33 | pos43 | | | | | | |-------------------------------| | | | | | | pos12 | pos22 | pos32 | pos42 | | | | | | |-------------------------------| | | | | | | pos11 | pos21 | pos31 | pos41 | | | | | | --------------------------------- How to adapt SHAPES' icon menu does not have to be a matrix of SHAPES to four columns and four rows. To change the matrix your needs: of the icon menu requires three steps. First, you must define new values to replace the current values specified in SHAPES.CDL for the number of columns and for the number of rows in the matrix. For example, if the number of columns were six, and the number of rows were five, the icon menu's matrix would contain thirty squares into which you could display icons. After you have changed the values for the number of columns and rows, you must adjust the number of positions in each column specified in SHAPES.CDL to reflect the new number of squares in each column of the matrix in which you may display an icon. Then, you must change the scale factor in each of the CADL icon files that are already listed as subroutines in SH_SCRN.CDL so that each icon will be displayed properly in the modified icon-menu matrix. (All the CADL files on this diskette whose names follow the pattern SH_xxx.CDL or I_xxx.CDL are subroutines of SHAPES. The names of the icon files follow the pattern I_xxx.CDL.) It is necessary to enter each icon file and change the scale factor individually because these icon files do not have the same scale factor for display. Some of the current CADL icon files listed in SH_SCRN.CDL are: I_OPNSL.CDL - an open slot composed of two parallel lines closed at one end by an arc. I_RNDSL.CDL - a round slot composed of two parallel lines closed by two arcs. I_SHRPSL.CDL - a sharp-cornered slot composed of two parallel lines closed by two arcs. I_RADSL.CDL - a radial slot composed of two parallel arcs closed by two arcs. I-OVAL.CDL - an oval. How to use: FILES - CADL - EXECUTE, enter: shapes After the screen has displayed the SHAPES menu, select the icon that you want with the cursor. You may use a mouse or the arrow-direction keys on the keyboard to move the cursor into the square containing the desired icon. As long as the cursor is inside the square, it will select the CADL file represented by the icon in that square. After you have selected the icon from the menu, the screen displays the icon with labels identifying the different dimensions that you must specify to enter the geometry represented by that icon into your part file. The bottom of the screen also displays a prompt referring to the the dimension's name and giving a default value for that dimension. Enter the required data. The screen prompts you for the location in which you want the geometry placed in your part file. Enter the location. CADKEY creates the geometry in your part file in the location that you have specified. The screen now asks whether you want the geometry's centerlines. The default answer is YES. After this, you can place this geometry in another location if you want to do so. If you prefer to enter a different shape into the part file, use BACKUP or ESCAPE to exit from the CADL file represented by the icon that you had selected. The screen displays the icon menu again. You can select another icon, activating the CADL file that it represents, and repeat the process described above. Or, you can exit SHAPES. To exit SHAPES, use <ESC>. You are now back in your part file in CADKEY.
