Thanks for the welcome!
Good to be back in the saddle after 25 years away from Autocad.
There is a lot of code in your example so maybe i did a cut and paste wrong or something but I am getting an error: "; error: syntax error".
Can you look at your code (i did the cut and paste a second time, no luck) and see if there is a syntax error?
just as a note, what I am trying to accomplish (the long goal) is to cut a section of a wall and create a simple door to place in the cut wall. i made a program like this back in the day but no longer have access to that code. so to help me re-learn autolisp i thought that i would do this project.
thanks for all your help.
