deferred class BooleanOperation from BRepAlgo inherits MakeShape from BRepBuilderAPI
---Purpose: The abstract class BooleanOperation is the root
-- class of Boolean operations.
-- A BooleanOperation object stores the two shapes in
-- preparation for the Boolean operation specified in
-- one of the classes inheriting from this one. These include:
-- - Common
-- - Cut
-- - Fuse
-- - Section.

is
Initialize (S1,S2 : Shape from TopoDS);
---Purpose: Prepares the operations for S1 and S2.
