CentralAngle Property (EllipticArcBuilderEx)

In This Topic

Gets or sets the central angle in radians.

Syntax

C#
Visual Basic (Declaration)

public double CentralAngle {get; set;}

Public Property CentralAngle As Double

Property Value

A double representing the central angle.

Exceptions

Exception	Description
System.ArgumentException	The CentralAngle is NaN.

Remarks

The central angle is the angular measure between the StartAngle and the EndAngle. It is measured in radians and is always between -2 * PI and 2 * PI. If the elliptic arc is oriented in a counterclockwise direction, then the central angle > 0. Otherwise, the central angle < 0. Changing the central angle may also change the end point, end angle, and orientation.

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;

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3 or higher.
