I've got a bunch of assemblies using parts that were created based on library parts, but are substantially different. Problem is, every time I load an assembly, solidworks pulls the library part. Even if you save as, make independent, move files around, etc, solidworks seems to sense that it was once a part related to a library part and replaces it every single time. This is a problem because I didn't tell it to replace it, I don't want it replacing it, etc.

Is there any way at all to unlink those parts?
