Yes, thank you helping me discover this.
I made a large enough triangle that has
enough plane-ness for my purpose. Great!

However, one important problem left: the plane
of the triangle is always solid, so I cannot
(partially) see through. How can I make
that transparent 80 percent or so ?

Thanks,
Rob.

PS: I'm surprised one can easily draw a triangle,
but not an equaly simple plane-like square....
