Syntax

C#

public static Curve CreateCurve(
	IList<XYZ> controlPoints,
	IList<double> weights
)

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.
