double endAngle
)
Parameters
- plane Plane
- The plane which the arc resides. The plane's origin is the center of the arc.
- radius Double
- The radius of the arc.
- startAngle Double
- The start angle of the arc (in radians).
- endAngle Double

Exception | Condition |
---|---|
ArgumentNullException | A non-optional argument was NULL |
ArgumentOutOfRangeException | The given value for radius must be greater than 0 and no more than 30000 feet. |
ArgumentsInconsistentException | Start angle must be less than end angle. -or- Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance). |

If the angle range is equal to or greater than 2 * PI, the curve will be automatically converted to an unbounded circle.
