Hi Mike,

> Ehh... :-/ For some reason, that way ends up with unevenly distributed points.

Yes it does, and it's supposed to - it adds more refinement in areas that are bendy.

But it also at the same time uses a knot vector spacing for the generated curve so that the parameterization matches that point spacing.

So the actual curve that is generated there has an even parameterization and will generate the same kind of "no stretching or squishing" result even though it has a non-uniform distribution of control points.

The key quality of the curve that you want to have is not actually "evenly distributed control points" - the thing you are looking for is actually "evenly distributed parameterization". The result of Rebuild with "refit to tolerance" mode will deliver that despite having non-uniform control point distribution.
