Question

What is the purpose of the [Network_Name]_BUILDERR table that appears in my geodatabase after building my geometric network?

Answer

After building your geometric network, a message box has appeared listing the invalid features in your network. It mentions a [Network_Name]_BUILDERR table located at the workspace level in your geodatabase.

The feature classes you selected to participate in your network contained features that are invalid within a geometric network. Features may be invalid for these reasons:

· The feature has an empty geometry
· The feature’s geometry has multiple parts
· The feature’s begin and end vertex are the same
· The feature has a geometry with a zero length

Invalid features can also be created by the network building process. Polylines whose start and stop points are within the snapping tolerance specified in the network wizard, can result in features with same start-stop geometry.

The BUILDERR table is a user-managed table that lists the invalid features in your network. This table is used to identify invalid features in ArcMap. The features can be repaired or deleted.

For more information on the BUILDERR table and using it to identify invalid features, see ‘Network build errors’ in the ArcGIS Desktop Help.
