Non-uniform rational basis spline NURBS is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces which offers great flexibility and precision for handling both analytic shapes defined by common mathematical formulas and freeform shapes. It is very easy to create an organic shape modeling. But, user is quiet hard to re-modify when the model has been completed.

They are a way of defining curves in 3D space through mathematical formulas. NURBS surfaces are a method of 3D modeling using said curves to define object surfaces, as opposed to using a mesh based polygon subdivision method. The other geometry types that Maya provides are polygon and subdivision surfaces.

Non-Uniform refers to the parameterization of the curve. Insert knot : You are asked for a knot value between 0. The program checks that the knot multiplicity is not greater than the order. This option can be used to have more points defining the same surface. The knot vector is an additional feature of the Nurb representation. The curve is a function P u that returns a point P on the curve for a particular value of the parameter u. Click to place the CVs. The first CV looks like a hollow box; subsequent CVs are dots.

Hulls are drawn between the CVs as you place them. For each CV after the third one you place, the shape of the curve is drawn. Press Enter to finish the curve. Turn on either the Selected or Generated options. Click Extrude.

Use the controls in the Attribute Editor or Channel Box to edit the extrusion. Select the surface on which you want to draw a curve-on-surface. Draw a curve on the live surface. Click the mouse to input CVs in any view to create a curve. Solved by jneilon. Solved by davidveyhle. Converting to Nurbs is not a process in most software.

If you are doing this often it might be best to check out NPower's plugins not cheap. If this is a one time thing try out a Demo of Rhino and use the command MeshtoNurbs.

Works pretty good for most cases you can then export to IGES format. In Max It might be hanging since it creating a lot of patches from you surface or there is something wrong with the mesh. Max's nurbs commands are a bit limited compared to other software since it really isnt a native environment. Someone else might have a better trick. You may need to reduce the polycount to get it to work. Rhino is asking for UV mapping.

I suppose you can do a simple UV and see if that helps.. I am not sure about that one. Thats all. If your model is closed and don't have interwind polygons you don't have any problem.

But i don' t know your polygon count and hardware ability. I hope it does'nt make problem. First of all you can try box then sphere. If it works you can see is there a problem with your model. If it does'nt work that's the wrong way.
