Creates new NURBS curves in the scene by placing edit points.
Draw a curve by placing CVs or edit points
Create a curve connecting objects
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.
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.
Create vertical and horizontal guidelines at each point you create.
