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.

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 projectionHint parameter contains information about whether a geometry will cross the coordinate system horizons. If it doesn't, parts of the code that check this and intersect the geometry with the horizons can be omitted. This can dramatically improve performance. Use ISpatialReference3::ProjectionHint to initialize this parameter.

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.

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

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 densify(double maxSegmentLength, double maxDeviation) throws IOException, AutomationException
Converts Polycurve into a Polycurve composed of Line segments with length maxSegmentLength (or less) that are within maxDeviation of the original polycurve. If maxDeviation = 0, maxDeviation is ignored and Line segments with length maxSegmentLength are constructed with vertices laying on the original curve. All of the segments in the final polyline will be Lines.
If the maxSegmentLength is negative IGeometryEnvironment::AutoDensifyTolerance is used. IGeometryEnvironment::AutoDensifyTolerance default value is 0. This value can be explicitly set via IGeometryEnvironment::AutoDensifyTolerance.
If the maxDeviation is negative IGeometryEnvironment::DeviationAutoDensifyTolerance is used. The default value is 2*XYResolution * 100 (2/XYUnits * 100). This value can be explicitly set via IGeometryEnvironment::DeviationAutoDensifyTolerance.
In order to avoid the creation of too many segments, the geometry system uses a maxdeviation = 2*xyResolution * 100 as default value if maxSegmentLength is 0 and the maxDeviation is 0.
If the maxDeviation is positive but smaller than 2*XYResolution of the spatial reference then the maxDeviation used is 2*XYResolution * 100
NOTE: The default values given in this topic are subject to change without notice. If specific values want to be maintained we recommend using the methods on IGeometryEnvironment to set those explicitly.

Generalizes each part of a Polycurve 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 polycurve with nonlinear segments, the output curve may contain more vertices than the input curve, but all output segments will be linear.

Converts the Polycurve into a Polycurve containing only BezierCurve segments. If the maxAllowableOffset parameter is zero, each segment of the input Polycurve becomes a separate Bezier curve. If maxAllowableOffset if greater than zero, the polycurve is generalized first by the DouglasPoiker method using the maxAllowableOffset value. Bezier curves are then created for each of the remaining segments. The created BezierCurve polycurve is an approximation of the original polycurve. At each vertex, the adjoining BezierCurves have complementary tangents which creates a continuous (smooth) transition between segments.
As an alternative, compare IConstructCurve2::ApproximateByBeziers.

The GeodesicDensify method modifies a polyline or polygon by inserting vertices. The original geometry is interpreted as a sequential collection of "stops" on the Earth's surface. The inserted vertices define the shape of the shortest ground path connecting those stops. The geometry must be associated with a geographic coordinate system.
The maxSegmentLength parameter is in the units (usually meters) of the semimajor axis of the coordinate system's ellipsoid. The minimum allowable value for this parameter is 1/10,000 of the length of the semimajor axis. This minimum value will be used for densification if the input value of maxSegmentLength is less than that.
The image below shows the results of applying the GeodesicDensify method to a polyline representing a flight path with stops in Honolulu and Los Angeles. The original polyline is modified by adding additional segments that identify the shortest ground distance between these locations.

preserveFromToPoints: Boolean value that determines if the from/to points of a ring in the polygon need to remain located at ring indexes 0 and PointCount1 af the completion of the operation. Specify 'false' to improve performance of this operation.
closeRings : Boolean value that determines if the rings of the polygon must be closed prior to reconstruct the topology of the polygon. Specify false if you know that rings are closed or you are passing in spaghetti input that should not be checked for closure.
useXORRule: Boolean value that determines how the 'inside' of the polygon is determined. Specify true to use an evenodd counting rule: a point is inside the polygon if a horizontal line through that has encountered an odd number of boundaries to the left (overlapping boundaries count 1 for each overlap). Use this when the input consists of welldefined rings that need to be oriented correctly, have overlaps removed, etc. Specify false to use the default behavior, which iterates over a two step process: dangle removal, then "peeling off" of the largest unambiguous rings. This approach can remove more segments than the XORtrue approach, but is probably more appropriate for spaghetti input where segment overlaps should not be considered significant.

Returns TRUE if the geometry is topologically Simple (refer to the discussion for the Simplify method). If the geometry is not Simple, it may be necessary to call Simplify to enforce topological consistency. Editing a geometry can change the IsSimple state of the geometry.
ITopologicalOperator methods 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 geometries types.
The xy cluster tolerance value of the geometry's associated spatial reference is used by this method. If the goal of this method is to determine if a geometry can be persisted in an sde (or other integerbased) layer without alteration, you may wish to use the minimum xy cluster tolerance value (ISpatialReferenceTolerance::SetMinimumXYTolerance) before applying this method (don't forget to set it back).

 If the ArcObject component throws an exception.public boolean isKnownSimple() throws IOException, AutomationException
Returns TRUE when the geometry is aware that it is Simple. IsKnownSimple may return FALSE even if the geometry is simple as long as the geometry is not aware of its IsSimple state. Calling either IsSimple or Simplify makes the IsSimple state known to the geometry. Topologically altering the geometry makes the IsKnownSimple state FALSE until the IsSimple state is again checked.
Here is the status of the IsKnownSimple flag in some common situations:
IsKnownSimple = 'False'
 A nonempty newly created geometry. For example, creating a polygon using IPointCollection sets the flag IsKnownSimple = 'false' on that geometry.
 Geometry after projection (IGeometry::Project )

Simplify permanently alters the input geometry, making its definition "topologically legal" with respect to its geometry type:
The XY tolerance property of the geometry's associated spatial
reference is used during the simplify operation for polylines and
polygons.
This method first looks at the ITopologicalOperator::IsKnownSimple flag before starting processing. If the flag is 'true' then operation is interrupted and the geometry is considered simple. If the flag is 'false' then the geometry consistency is checked and the geometry is updated as needed.
ITopologicalOperator methods 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 geometries types.
When a polyline/polygon is cut, it is split where it intersects the cutter polyline. Each piece is classified as ‘left of’ or ‘right of’ the cutter. This classification is based on the orientation of the cutter line. Parts of the target polyline that do not intersect the cutting polyline are returned as part of the ‘right of’ result for that input polyline. If a geometry is not cut, the left geometry will be empty.
When using a multipart polyline to cut a single ring of a polyline, the orientation of the polyline paths is important. The cut piece of the ring must be on the same side of each cutting path as defined by the orientation of each path.

AutomationException
 If the ArcObject component throws an exception.public void constructOffset(IPolycurve inCurve, double offset, Object offsetHow, Object bevelRatio) throws IOException, AutomationException
ConstructOffset constructs the offset of the given input Polycurve. If the offset parameter is positive, the constructed offset will be on the right side of the curve (left side offsets are constructed with negative offset parameters). Tracing the curve from it's first vertex to the last will give you a direction along the curve. It is to the right and left respective of this direction that the positive and negative parameters will dictate where the offset is constructed. In these terms it is simple to infer where the offset of even horizontal polycurves will be constructed. The offsetHow parameter determines how outer corners between segments are handled. Rounded offset rounds the corner between extended offsets. Bevelled offset squares off the corner after a given ratio distance. Mitered offset attempts to allow extended offsets to naturally intersect, but if that intersection occurs too far from the corner, the corner is eventually bevelled off at a fixed distance.
This results produced by this method are sensitive to large offset distances, particularly when the offset distance is larger than the length of the segments in the reference geometry. The remove self intersecting arcs feature is particularly problematic when extremely large offsets are involved.
The sides of the curve are determined from the order of the vertices of the curve. Tracing the curve from the first vertex to the last will give you a direction along the curve it is to the right and left of this direction that the positive and negative parameters will dictate where the offset is constructed. In these terms it is simple to infer where the offset will be constructed.
One alternative is to use buffer to generate the offsets.

ApproximateByBeziers constructs a curve consisting Bezier segments that being the approximation of input polycurve inCurve. The maxDistance parameter defines the maximum distance between the vertices of the input curve to the generated curve. If maxDistance is zero then for each segment of inCurve there is one Bezier segment created for this geometry. The parameter smoothClosedParts defines whether or not the last segment of the input polyline curve which is closed should be smoothed with the first segment of the curve. The smoothClosedParts parameter is only used if both this geometry and inCurve are polylines. If this geometry or inCurve is a polygon then smoothClosedParts is overwritten and set to true.
The resulting geometry is a polygon or polyline depending on the type of "this geometry" rather than the type of inCurve. If "this geometry" is a polygon and inCurve is a polyline with any open path, an error is returned (result is an empty polygon).

DouglasPoiker Generalization algorithm, extended to operate in 3D
space, with a specified multiple of the internal 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.

 If the ArcObject component throws an exception.public void queryPoint3D(int extension, double distanceAlongCurve, boolean bAsRatio, IPoint pOutPoint) throws IOException, AutomationException
Returns the Point at a given 3D distance along the curve or
extended curve. If the distance is less than the length of
the curve, then the returned point is the point at that distance
along the curve. If the distance is less than zero, or
greater than the length of the curve, then the returned point is on
the curve specified by the extension method. The distance may
be specified as a fixed unit of measure or a ratio of the 3D length
of the curve.
