Which AutoCAD versions are supported?

RC-SECTION, RC-WALL and RC-STAIR need AutoCAD 2021 or newer on Windows. FERMA runs on AutoCAD 2013 or newer and on AutoCAD LT 2024 or newer.

Does it work on a Mac?

No. RC-SECTION and RC-WALL use Windows COM objects and do not run on AutoCAD for Mac.

What happens after I buy?

You get an email with your license key and the download link. Load the program in AutoCAD with APPLOAD and enter the key with the key command of the program, for example RCWKEY.

On how many computers can I use it?

A single license works on 1 computer, an office license on 5. To move a license to a new computer, write to support.

Do I still need to check the results?

Yes. The programs speed up drawing and preliminary design. A licensed engineer is responsible for the final design.
