Detailed Description

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.
