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 This method is obsolete.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. 

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.

Description 
IGeometry 
Provides access to members that describe properties and behavior of all geometric objects. 
Classes that implement IGeometry2
Classes 
Description 
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. 
GeometryBag 
An ordered collection of objects that support the IGeometry interface. 
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. 
TriangleFan 
A continuous 3D fan of triangles, where each triangle after the first shares an edge with the preceding triangle, and all triangles share a common pivot point. 
Triangles 
A collection of 3D triangles, where each consecutive triplet of vertices defines a new triangle 
TriangleStrip 
A continuous 3D strip of triangles, where each triangle after the first shares an edge with the preceding triangle.
