I have assembly that I want to be able to see the parts when I pick on them in the model tree. When I pick on a part in the model tree, all I get is a square envelope around the part of where it is in the assembly. I want to see the whole part and its outline. Is this a function of speedpak or what else maybe? Whatever it is, I want to be able to see the part and if it IS speedpak, how do I disable it please?
