I am trying to build an icosahedron from wood. I need 20 equilateral triangle faces, all 3 edges the same length and all 3 angles 60o. That part is easy enough to do. But I need the edges all beveled at 69.1o - to form the 138.2o dihedral angles when I assemble the faces. And that part I am having troubles with.
At first I thought I would draw a rectangle the same length of the triangle, and use the extrude tool to create a bevel. then duplicate the rectangle 2 times and rotate and align each of the 3 with one edge of the triangle. However that doesn't seem to be working for me at all. I am getting some very odd results where they overlap, and even ignoring that it doesn't look like it is making the proper angle on the bevel, even though I locked the extrusion's angle to 69.1.
Is there some easier method of doing this?
