1. Click Shape in the main tool palette.
2. Click Cone in the lower tool palette.
3. Name the object. Naming objects now makes them easier to select from the command line. This is nice when dealing with a large scene.
4. Set the U Step, V Step, Revolution, Radius and Length (z) parameters as desired.
5. Click OK to create the shape, or click Cancel to abort.

U Step - The number of vertices circling the cone. A higher value makes the cone rounder but may take longer to redraw and render. The minimum number is 3.
V Step - Represents the number of rings this cone will have. The minimum number is 2.
Revolution - How far to spin the spline which will form the cone. 360Á represents a full, closed cone.
Radius - The width (x) and height (y) of the finished cone. Length (z) - The depth (z) of the finished cone.
