About editing geometric network features
This topic applies to ArcGIS for Desktop Standard and ArcGIS for Desktop Advanced only.
While network features can be both created and edited in ArcGIS for Desktop Advanced and Standard, they are read-only in Basic.
Geometric network features store various mechanisms and behaviors that maintain the topological connectivity between them. ArcMap is tightly integrated with the geodatabase when it comes to editing network features.
You can use ArcMap editing capabilities to create new network edges and junctions. By using the ArcMap snapping environment, you can create these features while maintaining network connectivity on the fly.
Geometric networks that are projected on the fly cannot be edited within ArcMap.
Network feature classes can participate in composite relationships with feature classes within the same geometric network, provided that the features are not connected.
Network feature classes that participate in a geometric network cannot be renamed.
While z coordinate values can be used to define connectivity during the creation of a geometric network, they are ignored during network editing. Z coordinate values are not used to define or establish connectivity during editing, only x and y coordinate values are considered.
