•Subtraction cuts out the shape of the Operator from Target.
•Subtraction with upward extrusion cuts out both the shape of the Operator from the Target and its vertical projection from the bottom of the Operator shape to the top of the Target.
•Subtraction with downward extrusion cuts out both the shape of the Operator from the Target and its vertical projection from the top of the Operator shape to the bottom of the Target.
•Intersection keeps only the common part of the Target and the Operator.
