Why is it when I go from a "Shaded" view drawing to a "Hidden Line Removed" view that some parts of my assembly disappear from the drawing? At that point I have to go to "Hidden Line" view to see everything but I can see "Everything"!! So why does some of my stuff disappear? I have tried this on more then one assembly drawing and it seems to only happen on assembly drawings, when there are multiple parts in the assembly.
