At times I find it would be nice to be able to do a "cut" from a sketch on two parts in an assembly.
Here I have a 7 gage welded up box, the transparent part is a 14 gage cover. It would be nice in the assembly to just sketch a circle on the 14 gage cover and do a cut through both of these parts for my screw. I can see that this can be done in the assembly level, but the cut feature does not show in the part level. Normally the way I would do this is to put a hole in one part, do the cut, then go edit the other part, do a sketch (maybe even convert entities) and then do a cut on that part.
