I cannot, for the life of me, get a drill operation to work on my 3d (iges) object. The holes are in the object but I can't select them in Select Geometry at the beginning of the drill operation dialog.
I have tried to use Extract From Solid (nothing seems to happen or change). I have tried to project the lines to a surface (which I finally succeeded in doing after an hour of trying) but I am still not able to select the holes, nothing highlights.
What is the typical procedure to doing this? I can't believe it is this hard!
