Syntax

C#
public static Arc Create(
	XYZ end0,
	XYZ end1,
	XYZ pointOnArc
)
Visual Basic
Public Shared Function Create ( _
	end0 As XYZ, _
	end1 As XYZ, _
	pointOnArc As XYZ _
) As Arc
Visual C++
public:
static Arc^ Create(
	XYZ^ end0, 
	XYZ^ end1, 
	XYZ^ pointOnArc
)

Parameters

end0
Type: Autodesk.Revit.DB..::..XYZ
The start point of the arc.
end1
Type: Autodesk.Revit.DB..::..XYZ
The end point of the arc.
pointOnArc
Type: Autodesk.Revit.DB..::..XYZ
A point on the arc.

Return Value

The new arc.

Examples

CopyC#
// Create a new arc using two ends and a point on the curve
XYZ end0 = new XYZ(1, 0, 0);    // start point of the arc
XYZ end1 = new XYZ(10, 10, 10); // end point of the arc
XYZ pointOnCurve = new XYZ(10, 0, 0);   // point along arc

Arc arc = Arc.Create(end0, end1, pointOnCurve);
CopyVB.NET
' Create a new arc using two ends and a point on the curve
Dim end0 As New XYZ(1, 0, 0)
' start point of the arc
Dim end1 As New XYZ(10, 10, 10)
' end point of the arc
Dim pointOnCurve As New XYZ(10, 0, 0)
' point along arc
Dim arc__1 As Arc = Arc.Create(end0, end1, pointOnCurve)

Exceptions
