Name	Return Type	Description	Inherited From
C NurbsSurfaceData(NurbsSurfaceData)	None	Copy constructor.

Name	Return Type	Description	Inherited From
M Create(Int32, Int32, IList<Double>, IList<Double>, IList<XYZ>, IList<Double>, Boolean)	NurbsSurfaceData	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.
M Dispose()	None	Releases all resources used by the NurbsSurfaceData
M Equals	None	Determines whether the specified object is equal to the current object. (Inherited from Object )	Object
M GetControlPoints()	IList<XYZ>	Get the list of control points.
M GetHashCode	None	Serves as the default hash function. (Inherited from Object )	Object
M GetKnotsU()	IList<Double>	Get the list of knots in the u-direction.
M GetKnotsV()	IList<Double>	Get the list of knots in the v-direction.
M GetType	None	Gets the Type of the current instance. (Inherited from Object )	Object
M GetWeights()	IList<Double>	Get the list of weights.
M IsValid()	Boolean	Check if the object contains a valid NurbsSurfaceData.
M ToString	None	Returns a string that represents the current object. (Inherited from Object )	Object

Name	Return Type	Description
P DegreeU	int	The degree of the spline in the u-direction.
P DegreeV	int	The degree of the spline in the v-direction.
P IsRational	bool	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.
P IsValidObject	Boolean	Specifies whether the .NET object represents a valid Revit entity.
P ReverseOrientation	bool	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.
