The method to find common Vertices and Edges between faces
BRepOffset_Tool::HasCommonShapes(const TopoDS_Face&,
const TopoDS_Face&,
TopTools_ListOfShape&,
TopTools_ListOfShape&)
has been re-implemented using maps and renamed to BRepOffset_Tool::FindCommonShapes.
The new method
BRepOffset_Tool::FindCommonShapes(const TopoDS_Shape&,
const TopoDS_Shape&,
const TopAbs_ShapeEnum,
TopTools_ListOfShape&)
has been implemented to look for the common shapes of given type.
