We have translated few V4 model into V5, and brought them (CATprod) into an assembly. So now i have a main product and sub-products created from V4. And these sub-products have parts. But for some reason some of the imported CATpart have no part bodies that can be mated with other part bodes, but instead it only has CATpart. Even when I right click and edit it, it does not expand. However, if I open them in a new window, they show the part body and geometries and all that stuff...what's going on? How come I can't see those part bodies of only some CATParts? But see everything if I open them in a new window?
