class Surface from BRepAdaptor inherits Surface from Adaptor3d
---Purpose: The Surface from BRepAdaptor allows to use a Face
-- of the BRep topology look like a 3D surface.
--
-- It has the methods of the class Surface from
-- Adaptor3d.
--
-- It is created or initialized with a Face. It takes
-- into account the local coordinates system.
--
-- The u,v parameter range is the minmax value for
-- the restriction, unless the flag restriction is
-- set to false.
