Chapter 7. NURBS Curves and Surfaces > Creating Surfaces from Curves

Creating Surfaces from Curves

There are several commands in Maya that you can use to turn curves into surfaces. They include Revolve, Loft, Planar, Extrude, Birail, and Boundary.

To revolve a curve to make a vase:

1.
In the front view draw a curve for the shape of the vase’s profile, as in the Figure 7.32.

Figure 7.32. A profile curve illustrates the outline of the object used for revolving.


2.
Select the curve in object mode.

3.
In the Surfaces menu select the box next to Revolve (Figure 7.33)

Figure 7.33. From the Surfaces menu select the box next to Revolve to open the Revolve Options window.


The Revolve Options window opens.

4.
Select the axis you want the object to revolve around (Figure 7.34). We’ll use the y axis for our illustration.

Figure 7.34. The revolve axis is very important to the look of the final surface. You want to choose the axis that goes through the middle of the final surface.


5.
Click Revolve to create the surface of the vase.

If you get unexpected results, you may have the object revolving around the wrong axis.

6.
Press to increase the smoothness to see the full surface (Figure 7.35).

Figure 7.35. Increasing surface smoothness helps clarify where the actual revolved surface lies.
