Options

Knot Spacing

A "knot" is the parameter value at an edit point.

Chord: the new curve's edit points will be parameterized by the chord length of the curve in current units. The chord length is the cumulative straight line distance between consecutive edit points.The starting point of the curve has the parameter 0.0, and the ending point has the parameter equal to the total chord length of the curve.

Uniform: the new curve's edit points will have integral parameters: the first edit point will be parameter 0.0, the second will be 1.0, and so on.

Curve Degree

The mathematical degree of the curve created, which control the number of CVs per span: 1 (linear), 2 (quadratic), 3 (cubic), 5 or 7. The default is 3.

Progressive Degree

Turn on this option to see the curve immediately after two CVs have been placed, regardless of the value of Curve Degree.

This is accomplished by gradually increasing the degree of the curve as CVs are placed down, up to the final degree of the curve. After two CVs, the curve will have degree 1, after three CVs, the curve will have degree 2, etc.
