The NurbsSurfaceData type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | NurbsSurfaceData | Copy constructor. |
Methods
| Name | Description | |
|---|---|---|
 | Create | Construct NurbsSurfaceData based on NURBS surface data, where the weights are supplied. The NURBS surface will be (piecewise) polynomial if all the weights are equal, rational if not. Note: A rational polynomial is a quotient of two polynomials; this includes a polynomial, which can be thought of as a quotient with denominator equal to 1. |
| | Dispose | Releases all resources used by the NurbsSurfaceData |
| | Equals | (Inherited from Object .) |
| | GetControlPoints | Get the list of control points. |
| | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object .) |
| | GetKnotsU | Get the list of knots in the u-direction. |
| | GetKnotsV | Get the list of knots in the v-direction. |
| | GetType | Gets the Type of the current instance. (Inherited from Object .) |
| | GetWeights | Get the list of weights. |
| | IsValid | Check if the object contains a valid NurbsSurfaceData. |
| | ToString | Returns a string that represents the current object. (Inherited from Object .) |
Properties
| Name | Description | |
|---|---|---|
 | DegreeU | The degree of the spline in the u-direction. |
| | DegreeV | The degree of the spline in the v-direction. |
| | IsRational | Tells if the spline is rational or not. If it is true (rational), then the NURBS is a piecewise rational polynomial function. If it is false (non-rational), then the NURBS is a piecewise polynomial function. |
| | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. |
| | ReverseOrientation | If true, the surface's orientation is opposite to the canonical parametric orientation, otherwise it is the same. The canonical parametric orientation is a counter-clockwise sense of rotation in the uv-parameter plane. Extrinsically, the oriented normal vector for the canonical parametric orientation points in the direction of the cross product dS/du x dS/dv, which S(u, v) is the parameterized surface. |
