class Quilt from BRepTools
---Purpose: A Tool to glue faces at common edges and
-- reconstruct shells.
--
-- The user designate pairs of common edges using the
-- method Bind. One edge is designated as the edge to
-- use in place of the other one (they are supposed
-- to be geometrically confused, but this not
-- checked). They can be of opposite directions, this
-- is specified by the orientations.
--
-- The user can add shapes with the Add method, all
-- the faces are registred and copies of faces and
-- edges are made to glue at the bound edges.
--
-- The user can call the Shells methods to compute a
-- compound of shells from the current set of faces.
--
-- If no binding is made this class can be used to
-- make shell from faces already sharing their edges.
uses
Vertex from TopoDS,

Create returns Quilt from BRepTools;
Bind(me : in out; Eold, Enew : Edge from TopoDS)
---Purpose: Binds <Enew> to be the new edge instead of
-- <Eold>.
--
-- The faces of the added shape containing <Eold>
-- will be copied to substitute <Eold> by <Enew>.
--
-- The vertices of <Eold> will be bound to the
-- vertices of <Enew> with the same orientation.
--
-- If <Eold> and <Enew> have different orientations
-- the curves are considered to be opposite and the
-- pcurves of <Eold> will be copied and reversed in
-- the new faces.
--
-- <Eold> must belong to the next added shape, <Enew> must belong
-- to a Shape added before.
is static;
Bind(me : in out; Vold, Vnew : Vertex from TopoDS)
---Purpose: Binds <VNew> to be a new vertex instead of <Vold>.
--
-- The faces of the added shape containing <Vold>
-- will be copied to substitute <Vold> by <Vnew>.
is static;
Add(me : in out; S : Shape from TopoDS)
---Purpose: Add the faces of <S> to the Quilt, the faces
-- containing bounded edges are copied.
is static;
IsCopied(me; S : Shape from TopoDS) returns Boolean
---Purpose: Returns True if <S> has been copied (<S> is a
-- vertex, an edge or a face)

Copy(me; S : Shape from TopoDS) returns Shape from TopoDS
---Purpose: Returns the shape substitued to <S> in the Quilt.

---Purpose: Returns a Compound of shells made from the current
-- set of faces. The shells will be flagged as closed
-- or not closed.
