I am using MCX on a Vertical Milling Centre, making train wheels. There is a round donut shaped pocket that needs to be machined concentrically to the wheel. To do this i have drawn a solid model of the wheel, and used a surface pocket toolpath (because of the 1" rad at the bottom of the pocket.) My problem is the pocket toolpath also trys to helix out the open axle hole, even though i have not selected geometry other than the walls and floor of the pocket. When i try to make a containment boundary on the 2 edges of the pocket to stop this from happening, i get a 'nested boundaries not allowed (or something like that)' message..
lol --- thanks
