Geometrically Thinking
« on: October 24, 2020, 07:09:18 PM »
Anyone here good at geometry? I have been searching and cannot find the angle between adjacent faces on a regular icosohedron.

I need to build one and am trying to calculate the bevels for adjacent faces.

Can anyone help?

Wikipedia says the dihedral angle is 138.189689deg, so the bevel will be half that.

Rural thank you. That is perfect for what I need.

I can see you do a lot of fabricating.
