I’m trying to make a largish (20 cm across or so) octagon or hexagon out of
technic parts. I thought this would be easy, because I believed that the bent
technic beams (e.g. 32348) had a
135-degree angle, or at least some angle that would divide evenly into 360.
But this does not appear to be the case; when I connect these with same-sized
beams, the end does not connect up. I can sort of force it into a hexagon, but
the pieces are under a fair amount of strain that way. So I have two questions:
1. Does anybody know what odd angle these pieces really are?
2. Any suggestions for how to make a simple octagon or hexagon out of technic
parts?
Thanks,
- Joe

| (...) It would appear that they're approximately 126.8698976 degrees. That's from approximating some angles and noticing that what I think they were trying to do was to create the geometry such that a 3-4-5 right triangle was possible. DaveE (17 years ago, 10-Dec-07, to lugnet.technic, FTX)

| (...) Try approaching it in steps. Can you make an equilateral triangle out of Technic beams? Don't worry about making the angles rigid, just make a structure with three equal-length sides, connected near the corners (connected with something that (...)
