Revit 2026 API
ArcCreate(Plane, Double, Double, Double) Method |
Creates a new geometric arc object based on plane, radius, and angles.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.0.4.0 (26.0.4.0)
Syntax
public static Arc Create( Plane plane, double radius, double startAngle, double endAngle )
Public Shared Function Create ( plane As Plane, radius As Double, startAngle As Double, endAngle As Double ) As Arc
public: static Arc^ Create( Plane^ plane, double radius, double startAngle, double endAngle )
static member Create : plane : Plane * radius : float * startAngle : float * endAngle : float -> Arc
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
- The end angle of the arc (in radians).
Return Value
ArcThe new arc.

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.
