Not to mention, BricsCad is actually developing LISP further, ACAD stopped this activity years ago. (don't ask me how many years ago)
If you have a LISP written for ACAD it will most likely work in BricsCad.
BricsCad also has ACET tools that need to be loaded, they offer the download on their website. (to ensure all ACAD LISP will run)
Guido, you must have been searching Autodesk's site to conclude BricsCad has no LISP.
