When you make more sophisticated objects using NURBS, there are times when you'll…need to stick multiple objects together.…Now remember, a NURBS surface is basically just a deformed patch, so it's a…four-sided object that's been deformed into anything from a sphere to a cylinder…to basically anything else. But it always has four corners and four size.…Now if we wanted to create an object that had a juncture--say a character's arm…or anything that has one object protruding from another--we can't create that…using the simple patch topology.…
We need to use multiple patches and stick them together.…So, one of the easiest ways to do this is by using what are called Curves on Surface.…So let's take a look at how to do this.…Now a curve on a surface is basically just a curve that is stuck to a NURBS…surface or a NURBS patch.…So let's go ahead and create the most basic NURBS patch we can.…Let's create a NURBS > Plane.…So I'm going to go ahead and drag that on the grid and move that up.…
Now if we want, we can just draw a curve on this plane, and we can do that by using…
