java.lang.Object com.esri.arcgis.geometry.Envelope
public class Envelope
A rectangle with sides parallel to a coordinate system defining the extent of another geometry; optionally has min and max measure, height and ID attributes.
The Envelope coclass defines a rectangular shape by its minimum and maximum x,y coordinates. Therefore, an Envelope is always orthogonal to its SpatialReference. An Envelope may also define minimum and maximum z and mvalues, depending on the implemented IZAware and IMAware interfaces.

 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.

AutomationException
 If the ArcObject component throws an exception.public boolean touches(IGeometry other) throws IOException, AutomationException
Two geometries are said to touch when the intersection of the geometries is nonempty, but the intersection of their interiors is empty. Touches is a Clementini operator. For example, a point touches a polyline only if the point is coincident with one of the polyline end points.
Touches examples. Only "true" relationships are showed in this picture.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
Touch does not apply for point/point comparison.
If either one of the two geometries is empty, the geometries are not touched.

AutomationException
 If the ArcObject component throws an exception.public boolean contains(IGeometry other) throws IOException, AutomationException
The base geometry contains the comparison geometry (other) if the comparison geometry is a subset of the base geometry and the intersection of their interiors is not empty. Therefore a polygon does not contain any part of its 1D boundary. Contains is the opposite operator of Within.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
If geometry1 Contains geometry2, then geometry2 is Within geometry1.
An empty geometry does not contain another geometry. On the other hand, an empty geometry is contained in another geometry, unless the other geometry is empty.
Contains examples. Only "true" relationships are showed in this picture.

 If the ArcObject component throws an exception.public boolean within(IGeometry other) throws IOException, AutomationException
The base geometry is within the comparison geometry if the base geometry is the intersection of the geometries and the intersection of their interiors is not empty. Within is a Clementini operator. Within is the opposite operator of contains.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
If geometry1 is Within geometry2, then geometry2 Contains geometry1.
An empty geometry is within another geometry, unless the other geometry is empty.
Within examples. Only "true" relationships are showed in this picture.

 If the ArcObject component throws an exception.public boolean disjoint(IGeometry other) throws IOException, AutomationException
Two geometries are disjoint if their intersection is empty. Two geometries intersect if disjoint is "false". Disjoint is a Clementini operator.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
Two geometries are disjoint if either one is empty.
Disjoint example. Only "true" relationships are showed in this picture.

AutomationException
 If the ArcObject component throws an exception.public boolean crosses(IGeometry other) throws IOException, AutomationException
Two polylines cross if they share only points in common, at least one of which is not an endpoint. A polyline and an polygon cross if they share a polyline or a point (for vertical line) in common on the interior of the polygon which is not equivalent to the entire polyline. Cross is a Clementini operator.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
Cross only applies to polyline/polyline, polyline/polygon, or polygon/polyline relations.
If either one of the geometries is empty, the geometries do not cross.
Crosses examples. Only "true" relationships are showed in this picture.

AutomationException
 If the ArcObject component throws an exception.public boolean overlaps(IGeometry other) throws IOException, AutomationException
Two geometries overlap if the region of their intersection is of the same dimension as the geometries involved and is not equivalent to either of the geometries. Overlaps is a Clementini operator.
Only geometries that support the IRelationalOperator interface can be used as input geometries.
Overlaps only applies to polyline/polyline, polygon/polygon and multipoint/multipoint relations.
Two geometries do not overlap if either one is empty.
Overlaps examples. Only "true" relationships are showed in this picture.

AutomationException
 If the ArcObject component throws an exception.public boolean relation(IGeometry other, String relationDescription) throws IOException, AutomationException
Relation allows a general relation defined using the Shape Comparison Language to be determined between two input geometries. The Shape Comparison Language is based on the CalculusBased Method (CBM), as described and defined by Clementini and Felice, but has some extensions specific to working with vertexbased geometries and is fully described in the Technical Documents section of the ArcObjects Developer Help. Please refer to the Shape Comparison Language documentation for proper syntax and available functionality.
Note that at the current release, Relation only operates with straight lines.
Here is a VBA example of using the "RELATE" function to detect overlapping polylines. It assumes two polyline features are selected. G1 and G2 are placeholders for, in this example, the VBA variables r1 and r2.
