Loops are areas of the network where flow direction is ambiguous. Within a loop, resources can flow in either direction. Loops are expected with mesh networks, but usually indicate error conditions in radial networks. You can discover loops using the Trace tool with the Loops trace type set.
To learn more, see Utility network trace types.
To perform a network loops trace, the following requirements must be met:
Trace network loops
- Ensure the utility network is available in an active map view and click the Data tab under Utility Network on the ribbon.
The Utility Network Data tab is activated.
- Ensure one or more starting points exist in the map view. In the Tools group, click the Trace Locations command to open the Trace Locations pane. Set Starting Points and Barriers to use in the trace.
For tracing network Loops, starting points must be specified, while barriers are optional.
- On the Data tab, in the Tools group, click Loops in the tools gallery.
Use the down arrow to browse in the tools gallery for Loops.
The Trace tool opens for the utility network in the active map using the specific Trace Type.
- Apply additional configuration parameters as needed. Reference the Trace tool for a full list of tool parameters. Also see Configure a trace.
- Click Run.
Features participating in loops are returned as a single selection set. Loops are not tracked individually, so the number of loops is unknown.
If a valid subnetwork controller is not present or not connected to the specified subnetwork, an error is returned and the trace fails.
