Before I bend over too far trying to figure it out, is it possible to make a torus, using primitives, that is elliptical in the major radius but without changing the minor radius? I think it is not, because the minor radius is in ratio to the major radius, so scaling the primitive differently in X and Y will change both radii proportionally.
The same problem exists with rings, but you can get around that using different primitives, such as chords and n-discs, as I've done in the two files below. (I'm trying to make both a flat and a rounded version; I've figured out the L and the E, but not how to make the round-topped version of G and O.) So maybe there is some way using another kind of primitive?
