Syntax

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

Parameters

controlPointsIList. XYZ.

The control points of the NURBSpline.

weightsIList.Double.

The weights of the NURBSpline.

Return Value

Curve
The new Curve object.

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.
