Part not shown in model

I am working on an assembly and one of the parts does not show up.  It was fine and then one day doesn't appear anymore.  It is shown in the feature manage and isn't hidden, transparent, or supressed but is "invisible" in the assembly.  It seems to have started after upgrading to 2010.  When the part is opened it appears invisible with nothing there but all the correct features appear in the feature manager.  Any ideas?SolidworksParts And Features
