When I open or insert some drawings, I see this: Loading AEC Base... Loading AEC Project Base... Loading AEC Schedule Data... Loading AEC Architectural Base... Loading ABS Base... Loading Modeler DLLs. I am running straight AutoCAD. The drawing I'm opening is a 2D detail, not generated in ADT or ABS. So, why is it loading all this junk? It takes forever (relatively speaking, of course!). Can this info be "purged"? Is it tied to certain objects? Can I find out which objects? We know it has come from either ADT OR LDT just need a way to remove from files. Thanks.
