Hello, AutoCAD community,
The AutoCAD team wants to hear your impressions of AutoLISP, specifically around its availability in the 2024 release of AutoCAD LT.
Which routines are you most excited to use? Let us know in the comments below!

This thread is so messed up you need to start a new one.
I also cannot understand what you are asking, maybe because the previous message is lost in the mess.
thx

Please don't take it personally, it is just my personal opinion that Autocad should move on from LISP to python. Because python is the universal language and LISP is Autocad-specific. All the lisp scripts can be automatically translated to python: https://www.codeconvert.ai/lisp-to-python-converter. For free. I used the translator for a couple of lisp scripts. The resulting python code had like 40% less lines of code. It also translated comments from French and Italian into English automatically. Python syntax is simpler and easier. By using python the number of programmers should increase ten-fold.
This was of interest as well.

Tried to find when Pyautocad was introduced I don't think as long ago as Autolisp. Look at VBA Autodesk have dropped it in preference for .net. You need to talk to Autodesk if you want some form of answer.
PyAcad, Python Extension for Autocad/Intellicad https://pyacad.sourceforge.net/ is even older R12-R13. It’s C, blistering fast, but limited to old ads_ calls
It died in 2003-ish. Would never work with LT
Pyautocad seems to be around 2012-13-ish
it’s out of process ActiveX automation, so its horribly slow. I suppose it can be useful for some things.
Last commit was 9 years ago, won’t work with LT
PyRx, Python for AutoCAD, https://github.com/CEXT-Dan/PyRx 2021-current, C++ ObjectARX wrappers for Python, in process ActiveX automation. Inspiration taken from Pyautocad and PyAcad. Would never work with LT

I like Python and I like Autolisp. The truth is activating the Autolisp switch in AutoCAD LT was easy to do. Adding Python to AutoCAD would be a major new project.
