I am new to Draftsight being AutoCAD user for years. I am trying to use AutoCAD Lisp routine(s) in Draftsight and it does not work the way it used to in AutoCAD.

What are the differences in AutoLisp for AutoCAD and Draftsight? Where can I found a good documentation on DraftSight AutoLisp?

If I will not be able to make my Lisp routine run within Draftsight, I may drop the draftsight altogether...

Thanks
