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.
