Can anyone recommend a good book on AutoLisp and VisualLisp? I found some general Lisp books, but I'm not sure how different the Lisp variants are.
I also did not find in the old questions.
"Visual LISP Developer Bible," for example by David M. Stein. This is from 2004, but the AutoCAD autolisp / visual-lisp API has not changed in recent years.
You can view and download AutoLISP books at the following links: Autolisp Books
AutoLISP "ABCs AutoLISP" ( Shantaram). . , . , . - .
By the way, I am happy to answer any AutoLISP question you may have. Or you can visit AutoDesk forums or forums AUGI or Forums CADTutor.net
