Example

C#

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);

VB

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)
