Is there a way to Update drawings such as changing layers, etc without creating a dll and a commanmethod?
I would like to write a VS app that would make changes directly to the drawing and not have to use the commandmethod approach.
You would have to pay for RealDWG or use openDWG
I have no experience with this at all, but I want to get into it, & I have found this swamp article with intersting info about ObjectDBX
When you are linking into AutoCAD from an external program you would use ObjectDBX to access the properties of the object. However you still have to have a copy of AutoCAD running.
