[Visual Basic .NET]
Public Sub ConstructEndPointsChordHeight ( _
    ByVal from As IPoint, _
    ByVal to As IPoint, _
    ByVal isCCW As Boolean, _
    ByVal ChordHeight As Double _
)

[C#]
public void ConstructEndPointsChordHeight (
    IPoint from,
    IPoint to,
    bool isCCW,
    double ChordHeight
);

[C++]
HRESULT ConstructEndPointsChordHeight(

  IPoint* to,
  VARIANT_BOOL isCCW,
  double ChordHeight
);

[C++]
Parameters
from 

  from is a parameter of type IPoint*
to 

  to is a parameter of type IPoint*

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Constructs a CircularArc given the From Point, To Point, the desired orientation, and the desired Chord Height.

Remarks

-isCCW stands for "is counter clockwise"

ConstructCircularArc EndPoints Example

[C#]

    IPoint toPoint1 = new PointClass();
    toPoint1.PutCoords(50, 50);
    constructCircularArc.ConstructEndPointsChordHeight(fromPoint1, toPoint1, true, 100);

    String report = "Length : " + circularArc.Length + "\n" +
                    "Radius : " + circularArc.Radius + "\n" +
                    "Chord Height : " + circularArc.ChordHeight + "\n" +
