I see a lot here about going from SolidWorks into MasterCAM but the problem we have is this: The machinist imports the SW file into MC makes changes to accomodate tooling and then WE no longer have a valid drawing and can't find a way to bring it back into SW without having to completely redraw.  This shortcoming has kept us from upgrading from SW07.

How pray tell do I import a parasolid, iges or whatever back into SW and have anything I can work with?
