Hi Raven,

re:

No, the Subdiv plug-in works somewhat differently than applying subdivision in a poly modeling program.

In a poly modeling program you can apply subd smoothing which generates a denser mesh. There's a good overview here:

For SubD to NURBS surface conversion it's a little different. It isn't making polygon output in steps, it's trying to make a smooth "limit surface" result.
