Extruding a NURBS surface?

[johnarkensaw]

Hello all,
I am a Max user now learning Maya, and just getting used to NURBS modelling.
A very basic question - how do I extrude a NURBS surface, or curve?

Thanks

Surfaces->Extrude to extrude a curve.
You cannot extude a surface.
Also look into Edit NURBS->Offset surfaces

Just Creates a surface by sweeping a profile curve along a path curve.
