Join George Maestri for an in-depth discussion in this video Opening and closing NURBS curves , part of Maya 2013 Essential Training: 3 NURBS Modeling Techniques.
In Maya, NURBS curves can be either open or closed. So an open curve would be just…like a loose piece of string.…It and would have two discrete ends.…In a closed curve, those ends would be joined together so it would make a loop or a circle.…So let's go a head and take a look at how to move between open and closed curves.…So we're going to start by creating a curve.…So let's create a curve that's kind of an oval shape.…So I'm going to go into my top window here and do a Create > CV Curve. And I'm…just going to go ahead and sketch out a rough oval shape here.…
So as you can see, we've got an open curve.…We've got two discrete ends.…If we want to close it, we can do it very simply by doing Edit Curves >…Open/Close Curves. And when I do that, it closes up the curve.…Now it closes up the curve at the first vertice here, so I've got that here.…And this is this open rectangle vertice. That's my first vertex in the curve,…and this is my second Control Vertex. And if I wanted to, I can open this up…again, so if I go back, select the curve in Object mode, do Edit Curves >…
