I'm constantly having troubles, because Solidworks is switching configurations in my assembleys. For example, there's a part, which has two different configurations, when switching between open documents, the selected configuration of that part in the assembley changes without me doing anything. Also some parts appear to be invisible after switching and can only be made visible again by supressing and unsuppressing them. It's really annoying and absoluteley kills the workflow, something Solidworks 2021 is very good at. Anyone experiencing similar troubles of has a solution for that particular problem? thank you!
