Hi Burr,

> It's a very interesting Polygonal point structure to the bottle.

That's actually what an exact surface of revolution looks like.

When you have an untrimmed surface of revolution, when you turn on the points for it in MoI, you will get the points for an automatically rebuilt surface instead which is more friendly for point editing than the exact one that has fully multiple knots in it. If you edit the polygonal looking point structure, you'll see that if you pull points of that structure around it kind of splits into quadrant pieces rather than staying as a single totally smooth surface.

If a surface is trimmed though, that automatic rebuilding will not take place. In this case the surface is trimmed so that's why you see that squarish polygonal point structure.

If you untrim it by selecting all of its edges and pushing delete, then you'll see the rebuilt control points appear on it instead when you turn surface points on.
