1. CA: copy objects in an array way.

Select objects, pick a base point, and pick a direct point. Then type your distance to copy, or just press enter. You can create an array of grid lines, rebar dots, etc. at various spacings by using this command.

2. RA

This is similar to the CA command, except now you are rotating objects.

3. 7BRPURLINS

This command is for steelwork. Select purlin lines and enter lapping length. The code will find crossing lines (they can be columns or beams or trusses) and break each purlin at every intersection point and extend each purlin to both sides a distance exactly equal to your specified lapping length.

4. ARB

+ Call the "ARB" command from the command prompt or from the 7CAD ribbon panel. Then the app will ask you to select a LINE, or a POLYLINE, or an ARC.

+ Then the app asks you for the distribution code. You can type:

+ Just a number, like "12," enter. The app will draw 12 rebar dots. Rebar size is taken as half of the current dimension text size.

+ You can enter "12F20" for the distribution code. Then the app will draw 12 rebar dots. But remember, since "rebar dot" is assumed to be an annotative object, its size is still half the current dimension text size. The only difference here is the rebar dot is offset away from the selected line or polyline by a distance. This distance is equal to the radius of the rebar size.

+ You can enter the pitch "F16@150" or just "@150," and rebar dots will be drawn at the 150-pitch center to center.

+ Press the "Tab" key to toggle the rebar dots' position to top or bottom.

+ Finally, hit Enter to end the command

5. More Commands

From version 2.0, I added a bundle of drafting commands to this app. Click "More Commands" to show the 7CAD Lisp Instructive Palette that lists all new commands.

Featured commands in the additional bundle:

+ PLOTALL: select rectangle polylines or title blocks in model space to plot each to a PDF file

+ Text commands: run TA to copy a numeric text and increase the number continuously. Text Calculation T+ T- T* to sum or subtract or multiply numeric texts.
