I am trying to place 4 object on a sphere so that they are equidistant. I can do this by placing them at the 4 corners of a tetrahedron, and a tetrahedron is just 4 corners of a cube. (The cube is just a construction object that will go away.)
I put my object at 0,0,0, then rotate it 45 degrees on two axes. (I then translate it to the corner of the cube.)
See screenshot part 1
I know this worked because when I turn the look down the corner of the cube, I can see my object is perfectly aligned.

But when I add the sphere in, the object is not perpendicular to the sphere's surface.
See screenshot part 3
What have I done wrong? I'm pretty sure I'm doing the multiple axis rotation correct. I set the Transformation Orientation to Local so the rotations should be relative to the object, not Global.
(I can fix it manually by rotating X to about 54 degrees rather than 45, but that's pretty sloppy.)
What am I doing wrong? Or better yet, is there an easier way of placing 4 objects at equidistant angles from each other?
