class MakeFace from BRepLib inherits MakeShape from BRepLib
---Purpose: Provides methods to build faces.
--
-- A face may be built :
--
-- * From a surface.
--
-- - Elementary surface from gp.
--
-- - Surface from Geom.
--
-- * From a surface and U,V values.
--
-- * From a wire.
--
-- - Find the surface automatically if possible.
--
-- * From a surface and a wire.
--
-- - A flag Inside is given, when this flag is True
-- the wire is oriented to bound a finite area on
-- the surface.
--
-- * From a face and a wire.
--
-- - The new wire is a perforation.
