Our office has computers running both Full Versions and LT versions of AutoCAD. What happens to support files in drawings that are utilized in Full but are missing in LT, specifically Lisp functions? I want to start running lisp functions but what happens when a drawing, that has specific fields or blocks dependant on lisp functions, are opened by a LT user? I also have action recorder commands that use the same alias keys as basic commands. Will that pose a problem?
