To create a loft, follow these steps:
1. Switch to the Surfaces menu set (press F4).
2. Draw the two curves.
3. Select the curves in the order in which you want the surface generated.
4. Choose Surfaces
Loft or click the Loft icon in the Surfaces shelf ( ).
When you define more curves for the loft, Maya can create more complex shapes. The
more CVs for each curve, the more isoparms you have and the more detail in the surface.
Figure 5.2 shows how four curves can be lofted together to form a more complex surface.
Indeed, you can use almost any number of curves for a lofted surface.
Lofting works best when curves are drawn as cross-sectional slices of the object to be
modeled. Lofting is used to make a variety of surfaces, which may be as simple as tabletops
or as complex as human faces.

A revolved surface requires only one
curve that is turned about a point in
space to create a surface, like a wood-
worker shaping a table leg on a lathe.
First you draw a profile curve to create
a profile of the desired object, and then
you revolve this curve (anywhere from
0 degrees to 360 degrees) around a sin-
gle point in the scene to create the sur-
face. The profile will revolve around
the object’s pivot point, which is typi-
cally placed at the origin but can be
moved (as seen in the Solar System
exercise in Chapter 3, “Your First
Maya Animation”), and sweeps a new
surface along its way. Figure 5.3 shows
the profile curve for a wine glass.
The curve is then revolved around
the Y-axis a full 360 degrees to create the wine glass. Figure 5.4 is the complete revolved
surface with the profile revolved around the Y-axis.
