Hi Max, when you use Paneling Tools in Rhino, do you generate all planar panels with it? I'm not sure that the different parametric panels that you've seen being done with the Elephant node editor have that particular property. For example things done using flow along a curved surface will also have a non-planar curved base to the panel as well, and if you see something with quadrilateral surfaces in it, it doesn't automatically follow that those quads are planar even if they happen to be bounded by 4 straight lines. Just something to be aware of if you require planar paneling in particular.
