Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.3.0.0 (26.3.0.0)
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
ArcThe new arc.
Exceptions
| Exception | Condition |
|---|---|
| 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);
