Difference
An operation that subtracts one geometry from another (A minus B).
Category: Operations · Also known as: Subtract, Erase
Definition (expanded)
Difference removes the overlap area of the cut geometry from the target. In editors this is often called Subtract or Erase. If the cut geometry fully covers the target, the target disappears. Topology issues can make results unpredictable.
