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.
