Nurb Spline Create Curve(IList XYZ , IList Double ) 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.

F#

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 IList XYZ

The control points of the NURBSpline.

weights IList Double

The weights of the NURBSpline.

Return Value

Curve
The new Curve object.

Exceptions

Exception	Condition
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.
