To help get started in creating surfaces there are four preset :term:`NURBS` surfaces,
found in the :menuselection:`Add --> Surface --> NURBS Surface`, :menuselection:`NURBS Tube`,
:menuselection:`NURBS Sphere` and :menuselection:`NURBS Torus`.

   NURBS surface primitives.


There are also two preset NURBS surface curves (with only one control point on each V row):
*NURBS Curve* and *NURBS Circle*.

Note how a circle :term:`NURBS` surface is never filled, unlike its "real" curve counterpart...
