Online tips & tutorials haven’t helped me out with this problem so-far. I’m trying to figure out how to draw a tetrahedron, or pyramid with triangular base; the first of the platonic solids. I got as far as creating a single equilateral triangle as a base, but I’m not sure how I would then go from this into a pyramid shape. I tried extruding it upwards and then trimming a rotated rectangular piece off of it, but this doesn’t result in perfectly equilateral geometry.
Any help would be appreciated.
