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.
||The x -coordinate of the last control point of a NURBS.
||The y -coordinate of the last control point of a NURBS.
||The second to the last knot of the NURBS.
||The last weight of the NURBS.
||The first knot of the NURBS.
||The first weight of the NURBS.
||A NURBS formula.
NURBS is a common way to represent a curve mathematically. You can create a NURBS with the Freeform tool.
