When I simplify a part and then try to show it simplified it in an assembly with Assembly Features, it will not show the simplified part and only show the Designed Part.
I logged an ER with GTAC, but does anyone else have this problem and figured out a workaround?
I remember having that problem. Before I upgrade my hardware, I had a few parts I needed to show simplified.
Try the switched for simplified assembly vs. simplified part. I think the show assembly as simplified is what actually changed the parts display.
