📢 - Whats your thoughts on AutoLISP in AutoCAD LT 2024?

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!

I think is great that LT use LISP. 

One lips routine that I would like to work in LT is the EXTRIM.LSP routine. I know that file came free as part of the express tools for AutoCAD.

When you load and try to run it. Is not working because is looking for the express tools.

 

Can some one help me solve this little problem.

 

Looking forward to your replies.

I too was trying using Extrim just a few days ago, and indeed, it doesn't work (I think the Express Tools lisps use something that is installed along with the tools). BUT I managed to find another lisp that basically does the same, and even more as it let's the user delete the leftovers inside. It works, I used it. I'll try to attach the file here.

Thank you for attaching the Lisp file. I will try it later today and I will post my findings.

Does this mean that I can now use this extreeemely useful lisp in LT?

Not all Lisp-programs, because there are few lisp function unsupported, but I would say for usual LT Users: Yes!

 

Your concrete sample: Yes, this works in LT2024 as the most of other Lisp programs too.

Hello, 

 

I was running layoutstodwg lisp routine on 2023 full version I believe and it spit out 20 sheets in about 30 minutes.  I tried running it on 2024 LT and it took all day to spit out half that and it was still running?  thoughts?

Hi,

You forgot to post ot to link this tool, just a name isn't enough to make sure to know what you are talking about.

And why you asking here instead to ask the programmer or vendor?

 

Guessing: You are talking about https://jtbworld.com/autocad-export-layouts-to-drawings-layoutstodwgs-lsp ?

If yes: That are simple steps in this code, nothing special.

Have you test it with another file from another project too?

Test it with a file what is stored on a local drive!

 

And tell what Tool you are talking about

I am missing a debug function for LISP in AUTOCAD LT

None of my commercial Lisp applications is compatible with AutoCAD LT. IMO Lisp in AutoCAD LT is only useful for non-professional programmers who want to do some automation with simple Lisp programs.

And there is an extra hook: non-professional Lisp programmers need a minimum of response in case of an error. But there is absolutely none.

When somebody asks me if I prefer AutoCAD LT or an AutoCAD clone with a grown-up Lisp like BricsCAD, then I need not a second to think about my reply.

Lisp the second-oldest high-level programming language still in common use, after Fortran.  Similarly, as Fortran has evolved threw Basic, C++, Jave, C#, etc., Lisp also has evolved.  They each represent two very different ideas on the structure of a high-level language.  Lisp is very stack oriented.  The Fortran thread is array oriented.  While today their siblings can both use stacks and arrays historically this difference shaped much of the syntax of the language.

 

Lisp lost the competition.  MIT dumped its Lisp department many years ago and it moved across the river to Northeastern University.  I took my Master's Computer Science at Northeastern; we were forced to use a more modern derivative of Lisp extensively.  I became fairly good at it, but it made me appreciate the winning thread much more.  I better understand why Lisp is now a dead end.
