Good morning, please is it normal for my AutoCAD 2025 not to recognize the let, loop, dotimes, when, collect and dolist functions when coding using the lisp programming language ? if no, how can i solve this problem ? Thank you

Curious, has it work for you in lower version of AutoCAD? Otherwise use the equivalent in AutoLisp namely while , foreach, mapcar and repeat

those are common lisp functions most likely, while autocad supports autolisp which is a bit different.

Hi, i am new to lisp programming so i started with AutoCAD 2025. I don't think the while , foreach, mapcar and repeat functions are the exact substitutes

I'm sure its not the exact equivalent but we can write a subfunction to emulate those functions.

Tell us what you need to do.

Good discussion here on Common Lisp vs Autolisp
