Namespace: Autodesk.Revit.Creation
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)

Syntax

C#
public CurveByPoints NewCurveByPoints(
	ReferencePointArray points
)
Visual Basic
Public Function NewCurveByPoints ( _
	points As ReferencePointArray _
) As CurveByPoints
Visual C++
public:
CurveByPoints^ NewCurveByPoints(
	ReferencePointArray^ points
)

Parameters

points
Type: Autodesk.Revit.DB..::..ReferencePointArray
Two or more PointElements. The curve will interpolate these points.

Return Value

The newly created curve.

Examples

CopyC#
ReferencePointArray rpa = new ReferencePointArray();

XYZ xyz = document.Application.Create.NewXYZ(0, 0, 0);
ReferencePoint rp = document.FamilyCreate.NewReferencePoint(xyz);
rpa.Append(rp);

xyz = document.Application.Create.NewXYZ(0, 30, 10);
rp = document.FamilyCreate.NewReferencePoint(xyz);
rpa.Append(rp);

xyz = document.Application.Create.NewXYZ(0, 60, 0);
rp = document.FamilyCreate.NewReferencePoint(xyz);
rpa.Append(rp);

xyz = document.Application.Create.NewXYZ(0, 100, 30);
rp = document.FamilyCreate.NewReferencePoint(xyz);
rpa.Append(rp);

xyz = document.Application.Create.NewXYZ(0, 150, 0);
rp = document.FamilyCreate.NewReferencePoint(xyz);
rpa.Append(rp);

curve = document.FamilyCreate.NewCurveByPoints(rpa);
CopyVB.NET
Dim rpa As New ReferencePointArray()

Dim xyz As XYZ = document.Application.Create.NewXYZ(0, 0, 0)
Dim rp As ReferencePoint = document.FamilyCreate.NewReferencePoint(xyz)
rpa.Append(rp)

xyz = document.Application.Create.NewXYZ(0, 30, 10)
rp = document.FamilyCreate.NewReferencePoint(xyz)
rpa.Append(rp)

xyz = document.Application.Create.NewXYZ(0, 60, 0)
rp = document.FamilyCreate.NewReferencePoint(xyz)
rpa.Append(rp)

xyz = document.Application.Create.NewXYZ(0, 100, 30)
rp = document.FamilyCreate.NewReferencePoint(xyz)
rpa.Append(rp)

xyz = document.Application.Create.NewXYZ(0, 150, 0)
rp = document.FamilyCreate.NewReferencePoint(xyz)
rpa.Append(rp)

curve = document.FamilyCreate.NewCurveByPoints(rpa)
