ArcObjects Library Reference (Geometry)

IGeometry3 Interface

Provides rapid access to a geometry's extent in the x-y plane. Note: the IGeometry3 interface has been superseded byIGeometry5. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	GeometryType	The type of this geometry.
	GeoNormalize	Shifts longitudes, if need be, into a continuous range of 360 degrees.
	GeoNormalizeFromLongitude	Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
	IsEmpty	Indicates whether this geometry contains any points.
	Project	Projects this geometry into a new spatial reference.
	ProjectEx	Projects a geometry, optionally applies a GeoTransformation, and optionally densifies the geometry.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	QueryWKSEnvelope	Defines the specified wksenvelope to be the current extent of this geometry in the x-y plane.
	SetEmpty	Removes all points from this geometry.
	SnapToSpatialReference	Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
	SpatialReference	The spatial reference associated with this geometry.

Inherited Interfaces

Interfaces	Description
IGeometry2	Provides access to members that extend the IGeometry interface with a more sophisticated projection method.
IGeometry	Provides access to members that describe properties and behavior of all geometric objects.

CoClasses that implement IGeometry3

MultiPatch	A collection of surface patches.
Multipoint	An ordered collection of points; optionally has measure, height and ID attributes.
Point	A two dimensional point, optionally with measure, height, and ID attributes.
Polygon	A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes.
Polyline	An ordered collection of paths; optionally has measure, height and ID attributes.
