Hello everybody, I would like to use common lisp to program / script CAD application Autodesk Revit via its .NET API. API readme says: "API supports in-process DLLs only" What does it mean? Is there any chance to use RDNZL with this statement? (Sorry for dumb question..., I'm completely new in this area, I just wanted to use my quite good autolisp knowledge for scripting Revit application)? Regards Frantisek Stafek
