Truncated Cone

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

The Truncated Cone page

In the Truncated Cone page, the geometrical parameters for the Truncated 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 truncated cone curvature. The Straight segments option is an approximation using linear wires.

The Truncated Cone is defined by giving the Base Point coordinates, Base Radius, Top Radius, Aperture angle and orientation angles, Theta and Phi. A truncated cone is a surface which is defined uniquely by these parameters, as shown in Fig. 2. A truncated cone can degenerate into a cylinder, a cone, a disc, or a flat ring.

Once the geometrical parameters in the Truncated Cone page have been set, the Attributes page can be chosen, where the number of facets of the Truncated 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.
