ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.Geometry Namespace / EllipticArcBuilderEx Class / EndAngle Property
Example Version

EndAngle Property (EllipticArcBuilderEx)
Gets or sets the end angle in radians.
Syntax
public double EndAngle {get; set;}

Property Value

A double representing the end angle.
Exceptions
ExceptionDescription
The EndAngle is NaN.
Remarks
The end angle is the angle of the line defined by the CenterPoint and the EndPoint. If RotationAngle != 0, then the end angle is relative to the rotated SemiMajorAxis rather than the X-axis. The end angle is is measured in radians and is always between -PI and +PI. Changing the end angle may also change the end point and central angle.
Example
Elliptic Arc Builder Properties
// retrieve the curve's properties
EllipticArcBuilderEx builder = new EllipticArcBuilderEx(arcSegment);
MapPoint startPt = builder.StartPoint;
MapPoint endPt = builder.EndPoint;
Coordinate2D centerPt = builder.CenterPoint;
bool isCircular = builder.IsCircular;
bool isMinor = builder.IsMinor;
double startAngle = builder.StartAngle;
double endAngle = builder.EndAngle;
double centralAngle = builder.CentralAngle;
double rotationAngle = builder.RotationAngle;
ArcOrientation orientation = builder.Orientation;
