I have noticed recently that I have several parts within sub assemblies in my top level assembly that are not showing even though they are not hidden or suppresed in the feature manager.  If I selct the part in the feature manager (its icon shows yellow) hide it, then show it it reappears.  I have tried to rebuild and do ctrl+Q and that doesn't help.  If I open the sub assembly, everything shows up.

Has anyone else seen this?

Thanks,

Colleen
