Yes, sorry I yammered so much. I wanted to cover curve creation and parameterization, and closed, open, and periodic curves, rebuilding curves and surfaces. I also wanted to show you could smooth out the facets by rebuilding either the curves or surfaces to have more spans.

I wanted to cover the pit falls using maya nurbs tools which are very primitive and so little things like not rebuilding to uniform parameterization can cause unpredictable results and so people get frustrated with nurbs and just give up on trying to take advantage of them.

But there was just to much to cover and since I make these vids off the top of my head I realized I had to speed up and leave some things possibly unclear.

But I hope it helped and you are getting better results now.
