Find all features connected to a given set of starting points in your network with the Trace tool using the Connected trace type.
To learn more, see Utility network trace types.
The Connected trace travels a network based on connectivity and ignores traversability. To learn more, see Connectivity and traversability.
Requirements
To perform a connected trace, the following requirements must be met:
- The network topology must be enabled.
- One or more starting points must exist.
- When working with an enterprise geodatabase, the Input Utility Network parameter must be from a utility network service.
Trace connected features
- Ensure the utility network is available in an active map view and click the Utility Network tab.
The Utility Network tab is activated.
- Ensure that one or more starting points exist in the map view. In the Tools group, click the Trace command to open the Trace pane. Set starting points and barriers to use in the trace.
- On the Utility Network tab, in the Tools group, click Connected in the tools gallery.
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.
A set of connected features is returned as a result selection set.
Caution:
Performing a connected trace on a large dataset without specifying additional configuration parameters could result in the trace operation timing out by attempting to visit every connected feature within the utility network. It is recommended that you constrain the traced features by setting barrier features or specifying other trace configuration parameters. For example, when performing a connected trace, parameters within the Traversability section are set for a condition barrier on Device Status being equal to Open or Category being equal to Subnetwork Controller. This helps to confine the connected trace to the subnetwork for the starting point feature.
