Cone

The Cone command creates a cone-shaped structure.

To access this command, go to Draw > Wire Grid / Solid Surface > Cone in the main menu, which opens the Draw dialog box for the Cone. The dialog box comprises three pages: Cone, Attributes, and Materials, as detailed in Fig. 1.

The Cone page

On the Cone page, you can set the geometrical parameters for the Cone. You’ll find a combo-box with two options: Curved segments and Straight segments. Choose Curved segments for an exact representation of the cone’s curvature, while the Straight segments option provides an approximation using linear wires.

The Cone is defined by specifying the Vertex coordinates, Aperture Angle, Aperture Radius, and orientation angles, Theta and Phi. These parameters uniquely define the cone’s surface, as illustrated in Fig. 2.

After setting the geometrical parameters on the Cone page, you can move on to the Attributes page. Here, you can specify the number of facets for the Cone and choose whether it should be a wire grid or a solid surface. See Grid/Surface Attributes for additional parameters in the Attributes page and Wire Materials for parameters in the Materials page.
