I have been using gibbs for many years. One thing I have never been able to figure out is when cutting a slot with air wall at both ends and using cutter comp is to get the cutter to cut off the far edge of the part. I will cut down one edge move over and cut back on the other edge But the cutter never clears the the part completely on the far side. I either have to cheat and make the slot longer than needed or edit the far move.
