Figure 5.3
A profile curve is drawn in the
outline of a wine glass in the
Y -axis.
Figure 5.4
The revolved surface
A revolved surface is useful for creating objects such as bottles, furniture legs, and
baseball bats—anything that is symmetrical about an axis.
Extruded Surface
An extruded surface uses two curves: a profile curve and a path curve. The profile curve
is drawn to create the profile shape of the desired surface. It's then swept from one end of
the path curve to its other end, creating spans of a surface along its travel. The higher the
CV count on each curve, the more detail the surface will have. An extruded surface can
also take the profile curve and simply stretch it to a specified distance straight along
one direction or axis, doing away with the profile curve. Figure 5.5 shows the profile
and path curves, and Figure 5.6 shows the resulting surface after the profile is extruded
along the path.
