NURBSTo Row (Geometry Section)

Contains the x- and y-coordinates, position of the second to last knot, position of the last weight, position of the first knot, position of the first weight, and the formula for a nonuniform rational B-spline (NURBS).

A NURBSTo row contains the following cells.

Cell	Description
X	The x-coordinate of the last control point of a NURBS.
Y	The y-coordinate of the last control point of a NURBS.
A	The second to the last knot of the NURBS.
B	The last weight of the NURBS.
C	The first knot of the NURBS.
D	The first weight of the NURBS.
E	A NURBS formula.

Remarks

NURBS is a common way to represent a curve mathematically. You can create a NURBS with the Freeform tool.
