Download the file divmac.exe. This will provide you with all needed files.
It is a self-extracting zip file that includes the macro file, this file in text form, and a couple of sample icons you can use to customize your icon bars. It should be extracted into your working FastCAD 32 directory (fcad32 on most systems). |
DV1 divides lines with small line segments into a typed-in number of sections. To use, select the line to divide. Then type in the tick length factor. The larger the number the smaller the length of the tick mark in relationship to the line being divided. Then type the number of divisions. The line will then be divided accordingly.
DV2 divides any entity with points. To use, select the line to divide, and type the number of divisions desired. Then type the number of the color of points you wish to use. The script will proceed to place points until all have been placed.
DV3 divides entities with points and then erases the original line. To use, select the line to divide, type the number of points to be drawn, and type the color number of the points. When the script is done placing points, the original entities will be erased.
DV4 divides entities with circles, a circle centerpoint at each division. To use, select the entity to divide, and type the number of divisions. The size of the circles drawn depends on the number of divisions, the more divisions the smaller the circles. This script will draw circles between each division and not on the endpoints with entities such as a Line or a Spline. In a continuous entity such as a Circle, Ellipse, or Smooth Polygon, the entity is evenly divided into segments. This script is a useful way of dividing entities into divisions that can be snapped to by using the center modifier on each circle, later the circles can be erased if necessary.
DV5 breaks a line into as many equal segments as typed in. To use, select the line to divide, and type the number of segments desired. The line will be broken into as many equal segments as you typed in.
DV6 breaks lines into equal segments and places a point at each break. To use, select the line to divide and type the number of segments. Then type the color number for the points to be placed. The line will be broken into the specified number of equal parts and a point will be placed at each break.
The primary change involves syntax. FastCAD 32 macro lines do not end in a semicolon. As such, the trailing semi-colon from each line must be removed.
The SET command has been replaced by APND. Both commands are used for string concatenation. The SET command allowed multiple parameters, while the new APND command only accepts a single source variable or value. Thus, multiple APND statements are required where one SET statement previously sufficed. To create the string "<bear5,segdist" in the variable relcor5, note the different methods:
| DOS | Windows |
|---|---|
| SET relcor5 < bear5 , segdist |
GW relcor5 < APND relcor5 bear5 APND relcor5 , APND relcor5 segdist |
The GV command is now used instead of the CALC command to process arithmetic operations. When substituting the GV command, the equal sign (=) is deleted, and there should be no spaces between the operators and the operands.
SBANG and SDIST have been renamed GBRNG and GDIST, respectively.
Several IF statements are no longer available, such as IFLT (If Less Than) and IFLE (If Less Than or Equal). Use the IFP, IFZ, and IFN statements instead. Most testing statements can be suitably converted since the conditional statements can include arithmetic operators.
Another general change involves labels. The DOS version required the label be listed with a trailing colon. In the Windows version, labels must have a leading colon. For example:
Done: becomes :Done
The IFER command is now named IFERR. DOS IFER statements that were stacked at the end of a line (after a semicolon) must be moved to the next line.
Care should be taken that macro lines do not inadvertently end with a SPACE character. This can be tough to check because, on most text processors, spaces are impossible to detect except by running the cursor at the end of each line. Unfortunately, the presence of a SPACE character in an unintended position may render your macro inoperable. The only proper context for a trailing SPACE is at the end of a ^D statement. Such a SPACE separates the prompt from the typed-in user input.

One way to load the macros is to use the LOADMAC command [Macros > Load Macros], and selecting the file divide.mac. You can also copy the divide macro or macros you wish to use into the fcw32.mac file, so that it loads automatically with your other default macros.
Once these macros are loaded, they can be run by typing their name at the command prompt. Macros are named on the first line of the macro block. If you wish to rename the macro DV1 to D1, simply edit the first line of the macro block to read:
MACRO D1
You can also place custom macros into your menu. Doing so simply requires editing of the fcw32.mnu in a text editor. For instance, you might add the following line to the [Edit] menu:
Divide w/ticks:|DV1;
You also place all the macros into a nested menu (to save space). To do this, you can copy the following block of text into the [Edit] menu. Of course, you can modify the menu text to suit your preference.
------------: Divide>: w/ticks:|DV1; w/points:|DV2; w/points, erase line:|DV3; w/circles:|DV4; into segments:|DV5; into segments & points:|DV6;
A custom icon can also be created for any macro can also be placed on the toolbar of your choice. Do this by creating an icon and editing the fcw32.imn file in a text editor. A couple of examples:
|
#204,divide.bmp:[Divide w/ticks]DV1; |
| or | |
|
#204,divide5.bmp:[Divide]DV5; |
Of course, you can of course modify the graphics, placement, and functionality of these icons as you see fit. For more information on icon creation and placement, please see Technical Brief: FCW-05 Custom Icons in FastCAD 32.
