Building a geometric network using a geoprocessing tool

This topic applies to ArcGIS for Desktop Standard and ArcGIS for Desktop Advanced only.


Although geometric networks can be both created and edited in ArcGIS for Desktop Advanced and Standard, they are read-only in Basic

The Build Geometric Network wizard discovers the connectivity for a group of feature classes in a feature dataset and promotes them from simple feature types (lines and points) to network feature types (edges and junctions).

When you build a geometric network, the feature classes must already exist in the feature dataset. However, they can be empty. After the network has been built, you can add new network feature classes.

Geometric networks are built in ArcCatalog.
