In our set operation algorithm solids are generated and modified using primitive operations each of which has a corresponding inverse. The operations applied to the solid are stored in a tree structure which represents the solid design process. An inverse set operation is executed by applying the inverses of stored primitive operations in reverse order. Inverse set operations are more efficient because they rely less on geometrical calculation.A method for implementing invertible set operations is proposed.
