SW2005 SP0.1 I have an assy that has 4 subs in it. The main assy has the usual stuff at the top - Annotations, Design Binder, Lighting, planes, Origin. If I click the + on any of the subs, that stuff is not showing up, but if I click open another level down, they do show up. Also, if I open the sub, everything is as it should be. Anyone else see this? Solution? The ramification is that I can't mate anything to the system planes of the subs - I have to go a level deeper in the sub to get a plane. WT
