Not sure if this is a lagacy file issue or a common SWproblem but I often run across an assembly that loads with randomparts set to partial transparency. Normally I can correct by goinginto APPEARANCE - COLOR - ADVANCED and setting the transparencyslider back to zero. I'm currently dealing with an old SW01assembly that shows the transparency slider faded out (dissabled).Opening the parts individually loads the parts in their normalsolid state.
