IGeometricNetwork Interface

Provides access to members that manage properties and elements of a geometric network.

Product Availability

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

When To Use

Use the IGeometricNetwork interface to return general geometric network information.

Remarks

A geometric network is a collection of feature classes that participate in a network relationship. Each feature class has a topological role in the network and a network may have multiple feature classes in the same role. A feature dataset may have multiple networks but a feature class can only belong to one network. Every geometric network has an associated logical network.

The NetworkLoader object should be used for creating or building of geometric networks, in place of the GeometricNetwork object.

If you need to access the logical network directly for doing such things as tracing or navigating the network using a forward star, etc see the Network object help.
