Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.4.0.0 (26.4.0.0)

Syntax

C#

public static Arc Create(
	XYZ end0,
	XYZ end1,
	XYZ pointOnArc
)

Parameters

end0  XYZ
The start point of the arc.
end1  XYZ
The end point of the arc.
pointOnArc  XYZ
A point on the arc.

Return Value

Arc
The new arc.

Exceptions

ExceptionCondition
ArgumentNullException A non-optional argument was NULL
ArgumentsInconsistentException The vectors end0 and end1 are coincident. -or- The vectors end0 and pointOnArc are coincident. -or- The vectors end1 and pointOnArc are coincident. -or- Cannot create an arc. -or- Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance).

Example

C#

// 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);

VB

' 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)
