This is an AutoLisp app. The Lisp source code is in the installation folder. After installation, go to the Add-In ribbon tab and you can see the 7cad panel with my ARB command.

Note: If you don't see the app, or run "ARB" returns the error of "Unknown command", then you should check the APPAUTOLOAD variable at your Autodesk® AutoCAD® command prompt. Type "APPAUTOLOAD" and set it to its default value of 14. Then, run the command "APPAUTOLOADER" for AutoCAD to reload add-in apps.

+ "ARB" command can be called from the command prompt, or from the 7cad ribbon panel.

+ Then the app will ask you to select a LINE, 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 the rebar dot is an assumed annotative object, its size is still half the current dimension text size. The only difference here is rebar dot is offset away from the selected line or polyline a distance. This distance is equal to the radius of the rebar size.

+ You can enter pitch "F16@150" or just "@150", and rebar dots will be drawn at 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

See screenshots for more details of how it works, and how the output is set up.
