NurbsSurfaceData Class Members:

Name	Description	Inherited From
NurbsSurfaceData	Copy constructor.

Name	Description	Inherited From
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.

Name	Description	Inherited From
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	Determines whether the specified object is equal to the current object. (Inherited from Object )	Object
GetControlPoints	Get the list of control points.
GetHashCode	Serves as the default hash function. (Inherited from Object )	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 )	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 )	Object
