The Disc command is used to create a disc or circular surface.
To access this command, go to Draw > Wire Grid / Solid Surface > Disc in the main menu. This action will open the Draw dialog box for the Disc. The dialog box consists of three pages: Disc, Attributes, and Materials, as detailed in Fig. 1.
The Disc page
In the Disc page, you can configure the geometrical parameters for the Disc. Here, you’ll find a combo-box offering two options: Curved segments and Straight segments. Select Curved segments for an exact representation of the disc’s curvature. The Straight segments option provides an approximation using linear wires.
The Disc is defined by specifying the Center coordinates, Radius, and orientation angles, Theta and Phi. These parameters uniquely define a planar disc surface, as illustrated in Fig. 2.
After setting the geometrical parameters on the Disc page, you can move on to the Attributes page. Here, you can specify the number of facets for the Disc 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.
