Detailed Description

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.
