Example Version

Orientation Property (EllipticArcBuilderEx)
Gets the orientation of this elliptic arc.
Syntax
public ArcOrientation Orientation {get; set;}
Remarks
Changing the orientation may change the central angle, start angle, and end angle. The start point becomes the end point and the end point becomes the start point.
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;
