Join George Maestri for an in-depth discussion in this video Using NURBS Extrude, part of Maya 2013 Essential Training: 3 NURBS Modeling Techniques.
Extrude is another way to create a NURBS surface from curves, and how this…works is it a uses a profile curve and then extrudes it along a path, which is also a curve.…So here we have a very simple case here.…I have a circle, which I can use as the profile, and then just a simple Bezier…curve, which I can use as the path.…So, in order to do this, I select the profile first and then Shift+Select the…path last, which means that's the one that's glowing green. And then all I have…to do is do Surfaces > Extrude and it takes that circle and runs it along the…curve and I have an extrusion.…
Now, extrusions are great because you can actually use the path to change the…shape of anything here. So if I were to go into wireframe mode here, so if I…right-click over that path do and Control Vertex, you can see this is Bezier…curve and I can change it pretty much however I want.…Now the surface itself can also be changed. So let's go back into Shaded mode…here and select this surface.…Now we can change it when we actually do the extrude here. I'm going to go ahead…
