public void queryCoords(boolean ellipseStd, IPoint center, IPoint from, IPoint to, double[] rotationAngle, double[] minorMajorRatio, boolean[] isCCW, boolean[] minor) throws IOException, AutomationException
Given the EllipseStd value, returns the Center Point, From Point, To Point, Rotation Angle, Minor Axis to Major Axis Ratio, IsCounterClockwise value, and IsMinor value of the Elliptic Arc. If EllipseStd = TRUE, the From Point and To Point locations are relative offsets from the Center Point rather than the origin.
These are the necessary inputs for PutCoords, except in special cases (half ellipse, full ellipse, Central Angle = 0, and Minor to Major Ratio = 0) where the ArcOrientation must know which of these cases exists to ensure that the desired Elliptic Arc is unambiguous. Any of the output parameters can be set to nil if that info is not desired.

PutCoords creates an Elliptic Arc given the EllipseStd value, Center Point, From Point, To Point, Rotation Angle, Minor Axis to Major Axis Ratio, and the Arc Orientation. If EllipseStd = TRUE, the From Point and To Point locations are relative offsets from the Center Point rather than the origin.
Unless the coordinates of the From and To Points are exactly on the defined Elliptic Arc, PutCoords is likely to create an invalid Elliptic Arc. Therefore, it is highly recommended that another Elliptic Arc creation method is used unless all of the necessary input parameters are exactly known.

Creates an Elliptic Arc given the EllipseStd value, Center Point, From Angle, Central Angle, Rotation Angle, semiMajor Axis length, and Minor Axis to Major Axis Ratio. If EllipseStd = TRUE, the From Angle is relative to the rotated semiMajor Axis rather than the XAxis.
This is the recommended way to create an arbitrary Elliptic 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.

 If the ArcObject component throws an exception.public void queryCenterPoint(IPoint center) throws IOException, AutomationException
The CenterPoint is the point where the Major Axis and Minor Axis of the EllipticArc intersect. The CenterPoint is the point from which all angles and distances are calculated to create the EllipticArc. You must instantiate the Point before calling QueryCenterPoint. For example,
Dim pPoint as IPoint
Set pPoint = New Point
The QueryCenterPoint method should be used in performance critical situations, where the center point of several arcs needs to be retrieved. The point is populated (not created) by the method. For example, this can be used to get the center point of several arcs in a loop. Creating the point only once outside the loop may improve performance for large number of arcs.

public void queryPointAndDistance(int extension, IPoint inPoint, boolean asRatio, IPoint outPoint, double[] distanceAlongCurve, double[] distanceFromCurve, boolean[] bRightSide) throws IOException, AutomationException
Finds the Point on the specified extended curve nearest to the input point and the distance between those points. Also returns information about the side of the curve the input point is on as well as the distance along the curve that the nearest point occurs.
AsRatio is an input parameter that only affects the DistanceAlongCurve
distanceFromCurve is an output parameter that represents the minimum distance between the curve and the input point.
DistanceAlongCurve is an output parameter that represents the distance between the Frompoint of the input curve and the returned point on the curve.
bRightSide is an output parameter that tells if the input point is on the right side of the curve. The direction of the curve determines the right and left sides.
Note: The output geometry must be cocreated prior to the query. The output geometry is not cocreated by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.

 If the ArcObject component throws an exception.public void project(ISpatialReference newReferenceSystem) throws IOException, AutomationException
To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.
A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.
The Project method must be applied on highlevel geometries only. HighLevel geometries are point, multipoint, polyline and polygon. To use this method with lowlevel geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into highlevel geometry types.
If a geometry is projected to a projected coordinate system that can't represent the geographic area where the geometry is located (or if trying to move an xy coordinate from outside the projected coordinate system back into geographic), the geometry will be set to empty.
Note: This method can only be called upon the top level geometries (Points, Multipoints, Polylines and Polygons). If the from/to spatial references have different geographic coordinate systems, the Project method looks for a GeoTransformationsOperationSet. If the set of Geotransformations is present in memory, Project will use it to perform a geographic/datum Transformation. To use a specific geotransformation, use the IGeometry2::ProjectEx method.

The second input point is always the To Point of the constructed EllipticArc. The third point is the Thru Point of the EllipticArc and is always guaranteed to lie on the constructed EllipticArc. The fourth and fifth points may lie on either the constructed EllipticArc or the embedded extension of the EllipticArc. The first three input points are guaranteed to be used in the construction of the EllipticArc. The fourth and fifth points are used in preferential order as long as they do not create an invalid EllipticArc. All points used to construct an EllipticArc must lie on a Convex Hull, otherwise the fourth or fifth nonconvex points are discarded to maintain convexity. Zero input points defines an empty EllipticArc. One input point defines a degenerate IsPoint EllipticArc. Two disjoint input points uniquely define a degenerate IsLine EllipticArc with the points at the end of the semiMajor axis with a Minor/Major Ratio of 0. Three noncolinear input points uniquely define an IsCircular EllipticArc in the same manner as ConstructThreePoints constructs a CircularArc. Four input points on a convex hull may be sufficient to uniquely define an unrotated (or Pi / 2 rotated) EllipticArc. For cases where an unrotated EllipticArc cannot be fit to the input points, a reasonable rotated EllipticArc is constructed to fit the input points (this EllipticArc is not the only rotated EllipticArc that can be fit to the input points.).
