ArcGIS Pro 3.0 API Reference Guide
ArcGIS.Core.Geometry Namespace / EllipticArcBuilderEx Class / CreateEllipticArcSegment Method / CreateEllipticArcSegment(MapPoint,MapPoint,Double,Double,Double,MinorOrMajor,ArcOrientation,SpatialReference) Method
The start point of the elliptic arc.
The end point of the elliptic arc.
The length of the semi-major axis.
The ratio of the length of the semi-minor axis to the length of the semi-major axis. The absolute value must be < 1.
The angle in radians by which the ellipse is rotated from the X-axis. A positive value corresponds to counterclockwise rotation.
The enumeration value indicating whether the arc is a minor or major arc. A minor arc is an arc such that the central angle is less than PI radians.
The value indicating if the arc is oriented clockwise or counterclockwise.
(Optional) The spatial reference. The default value is null. The spatial reference of the start point is ignored.

    CreateEllipticArcSegment(MapPoint,MapPoint,Double,Double,Double,MinorOrMajor,ArcOrientation,SpatialReference) Method
    In This Topic
    Convenience method to create a new instance of the EllipticArcSegment class. The new instance will be an elliptic arc.
    Syntax

    Parameters

    startPt
    The start point of the elliptic arc.
    endPt
    The end point of the elliptic arc.
    semiMajorAxis
    The length of the semi-major axis.
    minorMajorRatio
    The ratio of the length of the semi-minor axis to the length of the semi-major axis. The absolute value must be < 1.
    rotationAngle
    The angle in radians by which the ellipse is rotated from the X-axis. A positive value corresponds to counterclockwise rotation.
    minorOrMajor
    The enumeration value indicating whether the arc is a minor or major arc. A minor arc is an arc such that the central angle is less than PI radians.
    orientation
    The value indicating if the arc is oriented clockwise or counterclockwise.
    spatialReference
    (Optional) The spatial reference. The default value is null. The spatial reference of the start point is ignored.
    Exceptions
    ExceptionDescription
    startPt or endPt is null or empty.
    semiMajorAxis, minorMajorRatio or rotationAngle is NaN.
    An elliptic arc construction operation was given invalid axes. The absolute value of minorMajorRatio is > 1.
