AutoLisp File Locations

[jcb777]

I was doing a bunch of Lisp programming back in the day (r12-13) and then got focused on other things. I'm having some issues on where Autodesk is putting the lisp files in 2013, and is acad.lsp the defacto customization file still, if not what is.

acad.lsp contains the stuff I only need loaded once per session (mostly updating customizations located locally.
acaddoc.lsp contains the stuff I want to have loaded in every drawing.
you can put lisp files anywhere you want, as long as their path is added to the support file search path.

Acad.lsp still exists, but Acaddoc.lsp has taken over, like acad.lsp, this is a file you create.
You should put this some where AutoCAD can find it but not within the AutoCAD OOTB file structure so it doesnt get deleted with upgrades etc.

Do a search here in AUGI on "acaddoc.lsp" and you'll see all kinds of discussion and info on the subject.

For general LISP routines I load and use, I have a folder C:\Lisp

Good Luck!
