I have a customers part I am trying to unfold and send to mylaser. The problem is that my customer added a bunch of holes atthe assembly stage? When I open the part I want to unfold the holesare not there as well as when I unfold the part?

How do I get these holes in the piece part from the assy? I couldmake a sketch in the part stage and add them in but there must bean easier way?
