I'm exploring Blender's NURBS functionality. So far, I've been able to define two curves and create a NURBS surface between them.
It's fine if the interface is still lacking. If the functionality is available at all, I'll probably want to use it.
FWIW, I'm interested in NURBS because I do a lot of mechanical modeling. Meshes work for that, but NURBS are a much cleaner way to model a lot of man-made objects.
