There are also two preset NURBS surface curves (with only one control point on each V-row): *NURBS Curve* and *NURBS Circle*. .. figure:: /images/modeling_surfaces_introduction_primitives-curve.png NURBS curve primitives. Note how a circle :term:`NURBS` surface is never filled, unlike its "real" curve counterpart...
