In This Topic

Convenience method to create a new instance of the EllipticArcSegment class. The segment will be a circular arc.

Syntax

C#
Visual Basic (Declaration)

public static EllipticArcSegment CreateCircularArc( 
   MapPoint startPt,
   double chordLength,
   double chordBearing,
   double arcLength,
   ArcOrientation orientation,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateCircularArc( _
   ByVal startPt As MapPoint, _
   ByVal chordLength As Double, _
   ByVal chordBearing As Double, _
   ByVal arcLength As Double, _
   ByVal orientation As ArcOrientation, _
   Optional ByVal spatialReference As SpatialReference _
) As EllipticArcSegment

Parameters

startPt: The point from which the arc starts.
chordLength: The length of the chord connecting start point to the end point of the arc.
chordBearing: The angle in radians of the chord connecting the start point to the end point of the arc.
arcLength: The length of the circular arc.
orientation: The orientation of the arc, clockwise or counterclockwise.
spatialReference: (Optional) The spatial reference. The default value is null. The spatial reference of the start point is ignored.

Exceptions

System.ArgumentNullException	startPt is null or empty.
System.ArgumentException	chordLength, chordBearing or arcLength is NaN.
System.ArgumentException	arcLength equals zero.
System.ArgumentException	chordLength is greater than arcLength or chordLength is 0.
