nanoCAD forum

I was able to load stl.lsp, when I run it I get the system error (see attached, page 1): Stl_Load_Error.pdf
My system and NC version is on page 2.
I have also uploaded the lisp file with supporting files: STL.zip to test.
My question is: Is it possible to run the lisp program in NanoCAD?
Also, Why am I not allowed to add files to Options>Standard directories?
Thanks for reading.

I've discovered GstarCAD and it runs my autolisp routines right out of the box, so I will now be devoting my efforts to that platform. Nanocad is good for the free option and I will recommend it to my colleagues for that option.
