One of the most valuable functions for mold design in Cimatron is the Ejector Pocket. In a single step, it allows you to assign a variable clearance depth and a diameter to any number of ejector pins, then use these values to cut holes in the mold plates. With so many simultaneous cuts being created in both closed and open solids, you may see an occasional result that looks more like an extrusion than a hole. This occurs when the system has inadvertently flipped the object direction of an open solid. The fix for this is to edit the Ejector Pocket function in the tree of the part that received the reversed holes and invert the solid direction.
