CreateCurve Method (IList(XYZ), IList(Double))

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: 17.0.0.0 (17.0.484.0)
Since: 2017

Syntax

C# 
public static Curve CreateCurve(
	IList<XYZ> controlPoints,
	IList<double> weights
)
Visual Basic 
Public Shared Function CreateCurve ( _
	controlPoints As IList(Of XYZ), _
	weights As IList(Of Double) _
) As Curve
Visual C++ 
public:
static Curve^ CreateCurve(
	IList<XYZ^>^ controlPoints, 
	IList<double>^ weights
)

Parameters

controlPoints
Type: System.Collections.Generic IList XYZ
The control points of the NURBSpline.
weights
Type: System.Collections.Generic IList Double
The weights of the NURBSpline.

Return Value

The new Curve object.

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.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions 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.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions ArgumentsInconsistentException Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance).
