## NURBSTo class

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). This information is specified in the X, Y, A, B, C, D, and E elements, respectively.

## Constructors

| Name | Description |
| --- | --- |
| [NURBSTo](#constructor) | Creates an instance of the NURBSTo class. |

## Properties

| Name | Type | Description |
| --- | --- | --- |
| [IX](#ix) | int | The zero-based index of the element within its parent element. |
