I’m trying to create a model of an equilateral tetrahedron. The video above shows one of the ways I’ve tried.
I start with an equilateral triangle and duplicate it.
I rotate the duplicate 60 degrees up on the X axis. So far so good.
Then I duplicate one of the cylinders, rotate it 30 degrees toward the center then 60 degrees up.
That seems like it should work, but as you can see from the end of the video, things don’t line up correctly.
Can anyone explain why this doesn’t work or give any suggestions on what else to try?
I’ve seen examples where a tetrahedron is build with the corners and diagonals of a cube, but that approach won’t work because I need cylinders connecting the points, and the cylinders have to be rotated into position (at least AFAIK).
