Hi Brian,

> the thought is of the potentials if MoI could produce a Polyhedron?

Hi Brian, here is a method for that:




Start by drawing a central polygon with Draw curve / Polygon / Center, then draw the 2 connected ones by Draw curve / Polygon / Edge

Then you want to rotate that polygon up along its edge, which you can do by using Transform / Rotate / Rotate axis.

But you need to get a snap point for the proper angle, so to do that you set up 2 vertical circles that trace the path of rotation and you can find the angle as a snap point where they intersect.

Once you have rotated one up, delete the circles and the other flat polygon, and use Transform / Array / Circular with 5 items to produce the other sides. You can use Construct / Planar to make planar surfaces out of all the polygons.

That constructs have of it, you can then mirror and do a Transform/Rotate to make the second half into place.

EDIT: also attached Dodecahedron.3dm finished model file.
