NurbSpline.CreateCurve(IList<XYZ>, IList<Double>) Method

NurbSplineCreateCurve(IListXYZ, IListDouble) Method

Creates a new geometric Curve object from NURBS curve data containing just control points and weights. The created curve may be a NURBSpline or a simpler curve such as line or arc.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public static Curve CreateCurve(
	IList<XYZ> controlPoints,
	IList<double> weights
)
Public Shared Function CreateCurve ( 
	controlPoints As IList(Of XYZ),
	weights As IList(Of Double)
) As Curve
public:
static Curve^ CreateCurve(
	IList<XYZ^>^ controlPoints, 
	IList<double>^ weights
)
static member CreateCurve : 
        controlPoints : IList<XYZ> * 
        weights : IList<float> -> Curve

Parameters

controlPoints  IListXYZ
The control points of the NURBSpline.
weights  IListDouble
The weights of the NURBSpline.

Return Value

Curve
The new Curve object.
Exceptions
ExceptionCondition
ArgumentException The number of control points must be at least 2. -or- The number of weights must be the same as the number of control points and all weights must be positive.
ArgumentNullException A non-optional argument was NULL
ArgumentsInconsistentException Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance).
Remarks
There must be at least 2 control points. The number of weights must be equal to the the number of control points. The values of all weights must be positive.
