-- Provides methods for comparing faces mutual
-- location.

---Purpose: Add faces of <S> as unique faces in the result.

---Purpose: Add faces of <S> as double faces in the result.

MakeShells (me : in out; AvoidFacesMap : MapOfOrientedShape from TopTools)
returns ListOfShape from TopTools is static;
---Purpose: Make and return shells.

returns Boolean from Standard;
---Purpose: check if <F2> is inside <F1> by edge <E>.
-- if <CountDot>, compute <Dot>: scalar production of
-- normalized vectors pointing inside faces, and
-- check if faces are oriented well for sewing
Normal (myclass; E : Edge from TopoDS;
