It would be nice to be able to exclude surfaces from the mill window roughing and reroughing seqences. this is available with mill volumes and some types of mill windows but not with the rough and re rough seqences.
The situation I have is I rough a part with several holes and protrusions using a mill window and a large diameter cutter. the holes are smaller diameter than the roughing cutter so the roughing cutter never drops in the holes. When reroughing the same Part to tighten corners (remove more stock in the corners) with a smaller diameter tool. that tool will drop into the holes which is not desired and there is no way top stop this from happening that I can see.
