Re: Scheme Figure

Hello Andrea, 

Your example file is really nice. It really illustrates how powerfull is
the hot Scheme Figure feature.

However in your example  you could enhance it a little so that the first
rectangle triangle is rectangle by construction and not because of the
initial position of the 3 points.

Thanks for your nice example.
