using IClone::IsEqual

When applying the AddGeometry method give either the before or after index and not both. Adding a Geometry to the collection as the first one is done by setting the before index as 0.
The spatial reference of the GeometryCollection is transferred
(objects projected if necessary) to any objects added to
it. However the spatial reference of the added geometry is not
transferred to the GeometryCollection. Always make sure to set
the spatial reference on the object GeometryCollection prior to add
other geometries to it to avoid creating invalid geometry. For
example, adding geometry objects to a GeometryBag that doesn't have
a welldefined spatial reference will set an undefined spatial
reference to all the objects added to the bag. Using this
GeometryBag may cause unexpected behavior with the
ITopologicalOperator::ConstructUnion method.

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).

AutomationException
 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.
