I want to thank everyone involved who help me get going with a collision error message.
Back on topic... I'm trying to build a plastic injection mold. I have all the layers turned off except for the "A" plate. My stock is picked for the insert size, went through the tool set up, selected what to cut... then created a tool path. It generated the tool path like the "B" plate was part of the stock how do I remove these air cuts?
