deferred class RibSlot from BRepFeat inherits MakeShape from BRepBuilderAPI
---Purpose: Provides functions to build mechanical features.
-- Mechanical features include ribs - protrusions and grooves (or slots) - depressions along
-- planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built
-- around giving thickness to a contour. This thickness can either be unilateral - on one side
-- of the contour - or bilateral - on both sides.
-- As in the semantics of form features, the thickness is defined by construction of shapes
-- in specific contexts. The development contexts differ, however,in case of mechanical features.
-- Here they include extrusion:
-- - to a limiting face of the basis shape
-- - to or from a limiting plane
-- - to a height.

--- Methods redefined from BRepBuilderAPI_MakeShape
IsDeleted(me : in out ; F: Shape from TopoDS)
returns Boolean from Standard
is redefined;
---Purpose: Returns true if F a TopoDS_Shape of type edge or face has been deleted.

---Purpose: Returns the list of generated Faces F. This list may be empty.
---C++: return const &

---Purpose: Returns a list TopTools_ListOfShape of the faces S created in the shape.

FirstShape (me)
---Purpose: Returns the list of shapes created at the bottom of
-- the created form. It may be an empty list.

FacesForDraft(me)
---Purpose: Returns a list of the limiting and glueing faces
-- generated by the feature. These faces did not originally exist in the basis shape.
-- The list provides the information necessary for
-- subsequent addition of a draft to a face. It may be an empty list.
-- If a face has tangent edges, no draft is possible, and the tangent edges must
-- subsequently be removed if you want to add a draft to the face.
returns ListOfShape from TopTools;
---C++: return const&

---Purpose: Returns a list of the limiting and glueing edges
-- generated by the feature. These edges did not originally exist in the basis shape.
-- The list provides the information necessary for
-- subsequent addition of fillets. It may be an empty list.
returns ListOfShape from TopTools;
---C++: return const&
TgtEdges(me)
---Purpose: Returns a list of the tangent edges among the
-- limiting and glueing edges generated by the
-- feature. These edges did not originally exist in
-- the basis shape and are tangent to the face
-- against which the feature is built.
-- The list provides the information necessary for
-- subsequent addition of fillets. It may be an empty list.
-- If an edge is tangent, no fillet is possible, and
-- the edge must subsequently be removed if you want to add a fillet.
