 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.

ReplaceSegments will return an error ("The index is either too large or too small") if the inputs are inconsistent. For example, specifying index = 4 on a polyline with only 2 segments.
On multipart geometry, segments cannot be replaced on more than one part at the time. For example, an error (("The index is either too large or too small") is returned on a polyline with two parts containing three segments each when specifying index= 2, incoming= 2, removal= 2. The error is returned because the first part doesn't contain enough segments to remove two segments starting at index = 2. This behavior is enforced for performance reasons. Please see the example.

public void reverseOrientation() throws IOException, AutomationException
ReverseOrientation changes the direction of the curve without changing the spatial position of the curve. The From Point and To Point of each Segment in each part of the curve are interchanged.
The ReverseOrientation method works the same way as the Arcedit FLIP command. It reverses the order of the vertices in the Curve.
Caution should be taken in using ReverseOrientation on Polygons. Since ReverseOrientation changes the direction of each Ring within the Polygon, all Exterior Rings become Interior Rings and vice versa.

A curve is closed if the From and To points of each part of the curve are equal.
IsClosed may still return TRUE if the curve consists of improperly constructed geometries (ex. noncontinuous paths). IsClosed only checks the location of the From and To points of each part, it does not check the internal parts for topological consistency.

 If the ArcObject component throws an exception.public void generalize(double maxAllowableOffset) throws IOException, AutomationException
Generalizes the Path into a generalized collection of Line segments. Generalize performs a DouglasPoiker Generalization algorithm with a specified maximum offset tolerance given as input. For Line segments, the Generalized output is a subset of the original input vertices. For nonLinear segments, the Generalized output contains points along all parts of the curve, not necessarily only the vertices.
For a path with nonlinear segments, the output curve may contain more vertices than the input curve, but all output segments will be linear.

Converts the Path into a Path containing only BezierCurve segments. The created BezierCurve path is a Generalization of the original path that has a maximum deviation of maxDeviation from the original path. If maxDeviation = 0, all of the original vertices are maintained. At each vertex, the adjoining BezierCurves have complementary tangents which creates a continuous (smooth) transition between segments.

public void close() throws IOException, AutomationException
Checks whether or not the From and To Points of the Path occur at the same Point. If the From and To Point have the same X and Y coordinates, the Ring is considered closed, and no action is taken. However, if the From and To Points are not at the same X and Y coordinates, a Line segment is added at the end of the Ring between the To Point and the From Point. This Line segment completes the Ring making it closed.
This method should generally not be called in a 3D context, due to the fact that Close() only compares X and Y and not Z vertex values. Instead, the first point in the point collection should be manually readded as the last point in the point collection to close the geometry.

 If the ArcObject component throws an exception.public ICurve getSubcurveEx(double fromDistance, double toDistance, boolean asRatio, boolean isCCW, boolean useRingOrientation) throws IOException, AutomationException
The GetSubCurveEx method creates a subcurve of a ring. The subcurve may include the ring origin. The result is always a path object which may be closed.
Parameters description:
fromDistance: (Input) A double that represents the distance along the curve which will define one of the subcurve's endpoints. The value can be positive or negative.
toDistance: (Input) A double that represents the distance along the curve which will define the other endpoint of the subcurve. The value can be positive or negative.
If the fromDistance and toDistance values are equal, the output is a closed path with fromPoint and toPoint of the path at the specified distance. The orientation may be reversed, depending upon the other parameter settings.
asRatio: (Input) A boolean value that determines whether or not the input distances are interpreted as a ratio of the total length. If 'True', a fromDistance of 0 is at the beginning of the curve and a toDistance of 1 represents the end of the curve.
isCCW: (Input) A boolean expression that decides which of the two possible paths fromfromDistance to toDistance is chosen for output: counterclockwise or not. This does not decide the orientation of the output path.
useRingOrientation: (Input) A boolean that determines whether the output path should follow the ring orientation or not. If bUseRingOrientation is true, the output subcurve must have the same orientation as the ring, even if it means that the subcurve starts at toDistance and ends at fromDistance. If bUseRingOrientation is false, the output subcurve always starts at fromDistance and ends at toDistance; it may have the opposite orientation as the original ring.

 If the ArcObject component throws an exception.public void constructRigidStretch(IPath srcPath, int stretchStartIndex, int startAnchor, int endAnchor, IPoint stretchEnd) throws IOException, AutomationException
For an existing Path, the ConstructRigidStretch method can be used to rotate and scale the shape of a Path, or just a section of the Path, to a certain point. This method is ideal for use in interactive rubbersheeting operations. ArcMap, for example, makes use of this method in the ‘Stretch geometry proportionally when moving a vertex’ option.
Parameters description:
srcPath: Input IPath object. The path to be stretched.
stretchStartIndex: Input Long that represents the index of the origin point on the path to be stretched.
startAnchor: Input Long that represents the start anchor. Typically 0 to represent the first point on the path.
endAnchor: Input Long that represents the end anchor. Typically pointcount1 to represent the last point on the path.

The Origin is the only point in the transformation guaranted to remain in the same location after the transformation is complete.
Note: Caution must be taken when scaling a CircularArc or a geometry containing CircularArc segments. Unless Abs(ScaleX) = Abs(ScaleY), the resulting CircularArcs will not retain the characteristics of the original geometry (since they remain CircularArcs).
