How do I change the displayed shape of a plane in 3D?
Strangely, a plane appears as a six-sided polygon. See: https://www.geogebra.org/3d....
I'd like it to appear as a simple and more elegant-looking parallelogram. How do I accomplish this?
Also, is there a way to draw an outline around the plane? (Yes, I know that a plane stretches everywhere to infinity, but an outline makes the plane more distinct and clearer.)
