I want to snap the center of the circular plane to the vertex of the tetrahedron while rotating the cone around the origin (keeping its' peak in the origin).
I have made a vertex at the center of the circular base, but it's not showing up in object mode, and does not appear to be interactive in a snapping manner.
I realize this could also be done just by knowing the angle (and, in this case, rotating along the X axis), but I'm not aware of an embedded way to determine it.
Generally, in dealing with symmetrical manipulations, it would be nice to have a snapping grid that conforms to certain form. The regular cartesian could then be called "octahedral" since there are 3 axes x,y,z , and the next in axis count would be "tetrahedral"(one I would be using in this example) which would have all the common options that constrict manipulation to given axes. Just a suggestion, or in case there's already an Addon, feel free to link.
