Nurbs smothness
 

I'd like to know how to improve the smothness that maya uses to draw a nurbs surface. Sometimes maya doesn't render nurbs surface as smoth as I wanted. If I increase the surface resolution(using rebuild surface), the surface appears more smooth, but i dont wanna do this. I think maya should do this to me, it should render nurbs as smoth as nessecery.
Now, I've just found that there is an attribute called tesselation->advand tesselation->primary tesselation options where you can set (best guest based on screen size) to U and V. Doing this maya renders the low resolution surface much better.
Then I'll change my question:

Is there a way to make a surface based on a closed curve that is not plane(So planar doesn't work)?

Well, you could planar THEN trim tha part you want to open

matt, I think aogor ment that the curve he has to begin with isn't planar.

And yes aogor, there is. Unfortunately, you're going to have to divide the curve into four segments to get it to work.

aargh. I can't remember the exact command (and this computer doesn't have Maya). But the tool you'll need is under 'surfaces' in the modeling menu (I think). Basically, pick two opposite curves of the four you have, then the other two (order doesn't otherwise matter), and maya will fill in the surface.

So, say your curve went from a straight line at the front, to a half-circle at the back, with the two sides simple straight lines (the half-circle stands 'up' out of the plane). The surface would start out flat at the front, then gradually morph to a curve over the distance, all the while keeping the ends of the curve down at the straight lines of the sides.

Although another way to do this is to loft the surface you need, by creating cross-sections of the desired curve....
