Go to Draw > Wire Grid > Cone in the main menu to display the Draw dialog box for the Cone. There are three pages: Cone, Attributes and Materials.

The Cone page

In the Cone page the geometrical parameters for the Cone can be set, Fig. 1. There is a combo-box with two options: Curved segments and Straight segments. Choose Curved segments for an exact representation of the cone curvature. The Straight segments option is an approximation using linear wires.

The Cone is defined by giving the Vertex coordinates, Aperture Angle, Aperture Radius and orientation angles, Theta and Phi. A cone is a surface which is defined uniquely by these parameters, as shown in Fig. 2.

Once the geometrical parameters in the Cone page have been set, the Attributes page can be chosen, where the number of facets of the Cone can be entered. Refer to Wire Grid Attributes > to see other parameters that can be set in the Attributes page. Refer to Wire Materials > to see the parameters that can be set in the Materials page.
