Automatic |
Adds a knot/knot line halfway between existing knots to maintain as uniform a structure as possible. Increases the knot density of a curve or surface to add more control points while maintaining an even knot distribution for better point pulling behavior. |
Midpoints |
Places markers half-way between the existing knots/knot lines that can act as guides for inserting knots midway between existing knots. |
Symmetrical |
Adds knots on both sides of the center of the curve or surface. |
Undo |
Reverses the last action. |

Select Yes to also remove kinks from the curve.
"Kink angle" is the tangent direction difference between two adjacent segments.
Any kinks with an angle smaller than MaxKinkAngle will be removed.
Removing a fully multiple knot (kink) from a degree-1 curve or surface merges the spans next to it into a linear span.
