Is there a way to detach an object class definition file? I very seldom create new objects in this project. Quick select grinds acad map 2014 64 bit to a halt - today when I started quick select acad generated a fatal error (CER_83360176).
It seems counter productive if you can't use quick select to clean layers for classification. If you have objects that are invalid to the class, and you can't use quick select to filter those invalid objects, what's the recommended workflow?
I found it easiest to delete the whole layer and fix it in an acad session that has a copy of the drawing without the class file.
