Response based upon memory only :-)

Was unable to do a one step loft. In order to get the solid, had to resort to Boolean union of separate parts.
Do not know why. Something like a torus of circles would only take one step.

Do not understand the "unwrap" question. Recall that 120 degrees was used for something.
The modular arithmetic may help make the 3 corners more equal in shape, since due to the rotation,
different corners meet up.
