I think I have tried everything, but I must be missing something. I need to setup zones (for clamping) in my part that will not be milled away. I plan to mill everything inside first, then relocate the clamps to the inside and finish by cutting the outer border.
This works fine for parts which have a nice pocket inside them, but if the pocket is not fully closed, FeatureCAM wanders out and cuts the outside of the part as well (where the clamps are).
I want to set a simple curve or whatever that a certain feature will never cross, how can I do that?
Or maybe I'm just working against the program. So how can I do it differently? Here's a picture of the part:
