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.
