I wrote a LISP routine for Auto CAD using notepad , Do you know how to make it work in CAD where do I put it?

is it lisp or vba? is it this code that you posted a question about before?:

there is a big difference is why I ask, if you are writing vba hold down alt then click f11 to bring up the editor in autocad. If its lisp make sure the file has a .lsp extension and use the "appload" command to load it. Once you get these details figured out you can create commands or toolbuttons to run your code automatically.

Also autocad comes with a good example of how to make excel talk to it using vba look in the sample directory where ever you installed autocad.

you may want to search around on the sites i link below, there is alot of info there, and try the autocad help files too.
