Hi, I have a problem with parts with references . When I open an assembly and check File Explorer for files loaded by SW i can see that some of parts are in bold (changed since opening) even if they are orange (read only) and have transparent icons (referenced components that are in memory but not open in SOLIDWORKS). I think SW rebuilds these files on opening and that triggers them to be seen as changed since opening. My question is how to stop SW from rebuilding them or what makes them need a rebuild even if they were rebuild before being saved. Hope I explained myself coherently enough for somebody to understand my problem/question :P
