Dear members,
I'm not sure may I say that BabaCAD (after release 1.3) is first LISP enabled and autolisp compatible freeware cad. I have to code some more commands (mirror,break,join) and final 1.3 release will be available soon.
I want to encourage you to test beta pre-release of BabaCAD 1.3 (babacad.com/bem). Others who don't want to bother with installation of 2.9Mb file, I uploaded a new screenshot of 1.3 version capabilities (gallery link on babacad site; last image demo1.dxf).
I wrote some lisps and upload on babacad.com/upload/lisp so everyone can download and see how it works (just type appload command in command line and hit enter to load lisp file).
Best regards,
Mirza
