It seems to be updating or regenerating the same part irrespective of which part I'm editing. It doesn't list the name of the part which part it is regenerating. All I know is that it has 115 features that it regenerates 8-10 times. It does this even if I open a part and close it without making any changes. In fact is will do it even if I hit cancel.
It looks like SW18 has changed something with the new file progress dialogs that now pop up when you open or save. FWIW things seem to be taking much longer to open as compared to '16.
In an assembly of ~800 parts, is there a way I can easily find which part is causing this rebuild problem?
