In-Depth Information
W e d g e
The wedge has a rectangular base and a lid that slopes up from one
edge of the base. You specify the base as you do with the Box primitive and then
enter the height.
torus
This is a donut shape. You specify a center point for the hole, the radius
of the circular path that the donut makes, and the radius of the tube that fol-
lows the circular path around the center point.
The other tools on the Modeling panel are for creating additional 3D solids,
for manipulating existing 3D shapes, or for using 2D shapes as components for
making 3D shapes. You've already used some of these tools, and I'll cover the
others here:
Planar Surface
Found exclusively on the Surface tab
➢
Create panel,
the Planar Surface tool creates a flat, rectangular surface that is seg-
mented in both directions. The segments are visible only when the object is
selected or in a Wireframe visual style (see Figure 16.93).

Revolve
Select a closed 2D shape, and then define the axis and the angle
of rotation. A Revolve object is shown on the left in Figure 16.94.
