Creates solid-filled triangles and quadrilaterals.
2D solids are filled only when the FILLMODE system variable is on (1) and the viewing direction is orthogonal to the 2D solid.
The following prompts are displayed.
Sets the first point in the 2D solid.
Sets the first edge of the 2D solid.
Sets the corner that is opposite the second point.
The fourth point is diagonally opposite the first point. Pressing Enter at the Fourth Point prompt creates a filled triangle. Specifying a fifth point creates a quadrilateral area.
Specifying successive third and fourth points creates further connected triangles and four-sided polygons in a single solid object.
