I am a big fan of custom buttons. I have created some that have rather lengthy an complex macros. We use Microvellum which runs on an AutoCAD platform to generate BOMs and CNC programs. When you install the program, it reconfigures AutoCAD using its own menu file. A recent upgrade has been ran and a ConfigureAutoCad2004.exe program ran. As a result, all my custom toolbars, buttons and their respective macros are gone. I realize that this may be a Microvellum issue and I have contacted them. But I figure that maybe someone knows of a quick fix. Thanks for any help. It would save me many hours trying to reconstruct all that customization.
