And the parts which are out of this region can be -- excluded from the result. uses SequenceOfRoots from IntTools, MarkedRangeSet from IntTools, SequenceOfRanges from IntTools, Context from BOPInt, ExtCS from Extrema, ProjectPointOnSurf from GeomAPI, Edge from TopoDS, Face from TopoDS, Curve from BRepAdaptor, Surface from BRepAdaptor, Box from Bnd, CurveRangeSample from IntTools, SurfaceRangeSample from IntTools, ListOfCurveRangeSample from IntTools, ListOfSurfaceRangeSample from IntTools, CurveRangeLocalizeData from IntTools, SurfaceRangeLocalizeData from IntTools, Surface from Geom is Create returns BeanFaceIntersector from IntTools;
