Very cool Peter, that turned out great!

If you need to make more things like this, let me know and I can give you some more detailed instructions on how I built that one.

The basic approach is to place the polygons flat down on the plane, and then use Transform / Rotate / Rotate axis to swing them up. But the tricky part is getting the angle for how far to rotate it, that requires setting up several intermediate curves and intersecting them.
