Hi,

I have an assembly of several components.  When I click on the main part (the first one I inserted into the assembly) and click on the "Open Part" folder icon, the part appears briefly on screen and then vanishes.  When I go back to the assembly, it is not visible there.  In both the files the part and its features are still visible in the Feature Manager design tree.  If I close those windows and try opening the part directly from its file, the screen just comes up blank.  Does anyone know how to fix this?

Thank you,

Brian
