I  have a frame weldment created and used in an assembly. There are about a dozen pieces of slotted unistrut  mated to the frame. The slots in the strut were created from a sketch and cut/extrude feature. The slots were then propagated with a linear pattern. Now that I have these pieces of strut positioned I need to put holes in the frame. I suppose I could just edit the frame in the assembly, dropping holes "close" to where they should be and clean up with the resultant sketch in the part file. I'm sure there is a better technique?
