Hi Burr, yeah every time you add in an additional knot in that area, it will reduce the stretch of the curve that is affected by the control points in that part of the curve.

The new Rebuild command has 2 modes to it, a "Refit to tolerance" mode where you give it a distance value, and it refines the rebuilt curve to use as many points as necessary to achieve that tolerance, or a "# Points" mode where you just tell it how many points you want it to use, that mode is like the current RebuidCurve plugin.
