The problem im having is that when you have a sequence retract plane at an angle of say 45 degrees, it will go above the operation retract plane at some points.
Eg: 
I just want to know if theres a possible way to limit the procedures retract plane once it hits the operation plane. The operation plane should be a limit of the height you wish to retract to. Is there any way at all to tell Creo not to go above a certain height?
