The Plate refers to a plate or bilinear surface.

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

The Plate page

In the Plate page the geometrical parameters for the Plate can be set, Fig. 1. The Plate is defined by giving the coordinates of four corner points. In general, a plate or bilinear surface is a non-planar quadrilateral, which is defined uniquely by its four vertices, as shown in Fig. 2. In this case, the bilinear surface degenerates into a flat quadrilateral.

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