ICircularArc.PutCoordsByAngle Method

Defines this circular arc by a center point, 'from' angle, signed central angle, and radius.

[Visual Basic .NET]
Public Sub PutCoordsByAngle ( _
    ByVal cp As IPoint, _
    ByVal FromAngle As Double, _
    ByVal CentralAngle As Double, _
    ByVal arcRadius As Double _
)
[C#]
public void PutCoordsByAngle (
    IPoint cp,
    double FromAngle,
    double CentralAngle,
    double arcRadius
);
[C++]
HRESULT PutCoordsByAngle(
  IPoint* cp,
  double FromAngle,
  double CentralAngle,
  double arcRadius
);
[C++]

Parameters

cp

  cp is a parameter of type IPoint

FromAngle   FromAngle is a parameter of type double CentralAngle   CentralAngle is a parameter of type double arcRadius   arcRadius is a parameter of type double

Product Availability

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

Description

PutCoordsByAngle creates a Circular Arc given the Center Point, the From Angle, the Central Angle, and the Radius.

Remarks

PutCoordsByAngle is one of the easiest ways to create a desired Circular Arc.  However, due to numeric accuracy limitations of computers and trigonometric functions, the From and To Points may be very slightly offset from the expected coordinates.  This is important to keep in mind when attempting to connect the endpoints to other segments.
