I had a question when setting up the FCS in a second operation or setup, like when you turn the part over and are starting to mill the backside. I understand that you go to the Cam Operation Tree and edit the definition of the Part Setup. What I do not understand is why I can not select certain Geometry as an entity for my Second Setup Coordinate System. I have attached a video to show what I'm talking about. Its a little long but I think it demonstrates what I'm talking about. Thanks!!!!
