package MgtBRep
---Purpose: The MgtBRep package provides methods to translate
-- data between the BRep package and the PBRep
-- package.
--
-- That is to translate persistent BRep data
-- structures in Transient BRep data structures and
-- vice-versa.
--
-- The MgtBRep package uses :
--
-- * The MgtBas package to bind a transient and a
-- persistent object.
--
-- * The MgtTopoDS package to provide basic methods
-- to translate TopoDS and PTopoDS data.
--
-- * The MgtTopLoc package to translate Locations.
--
-- * The MgtGeom, MgtGeom2d packages to translate
-- geometric data.
--
-- * The MgtPoly package to translate triangulation data.
--
-- The Translate methods has TriangleMode argument.
-- If it is MgtBRep_WithTriangle, the methods returns or
-- create a Shape with triangulation.

Translate1(aShape : Shape from TopoDS;
aMap : in out TransientPersistentMap from PTColStd;
aResult : in out Shape1 from PTopoDS;
aTriMode : TriangleMode from MgtBRep);
---Purpose: Translate a transient Shape to a persistent Shape.
-- The translation is performed according to the map aMap and the
-- triangulation specified by aTriMode.
-- The map, aMap, is a tool that lets you share
-- topological components. When the map is
-- initialized, it is empty. It is built up and used by the
-- Translate function every time a topological
-- component is converted from persistent to
-- transient and vice versa. This is true for all
-- topological components that can be shared:
-- vertex, edge, wire, face, shell, solid, and so on.
-- This map allows you to share individual
-- components as they are translated, and also lets
-- you share previously converted components
-- when you translate other objects which share
-- (i.e. refer to) these components.
-- The triangulation mode, aTriMode, specifies
-- whether a representation of the object as a set
-- of triangles - if such a representation exists - is
-- to be translated or not in addition to the
-- canonical definition of the object.
