Analyzing Network Topologies

You can analyze a network topology (sometimes called tracing) within predefined workflows or with the Network Tracer.

Use the Stop Condition Editor in the Workflows pane to specify a stop condition. You can use a predefined stop condition, or you can define a new one.

The Autodesk Infrastructure Map Server Administrator defines tracings and tracing conditions. You can see them if you defined a logical (network) topology.

Some data models (for example, in the Gas, Water, Wastewater, and Electric modules) have predefined tracings.

To analyze a network topology

1. In the Industry Model Explorer, click Industry Model Explorer.
2. In Industry Model Explorer, expand the Topologies item.
3. Right-click a topology and click Network Tracer.

   If your Administrator defined any other tracings, they also appear on this shortcut menu. If a tracing uses a stop condition, when you select it the Stop Condition Editor is displayed. You can often tell which tracings use stop conditions by their names.

   Note:

   You can also start the Network Tracer from the Workflow Explorer by selecting an Analyze workflow.

4. In the Network Tracer dialog box, in the Tracing Template list, select a template.

   Tracing templates are predefined tracing models (propagation) that are defined in the data model administrator.

5. Follow the on-screen instructions in the Features section.

   Workflows vary, depending on the tracing template.

   Note:

   The administrator defines network tracing templates in the data model administrator.

6. If you are tracing an attributive network topology, specify the start and end features in the feature class form.
   • Click Start Features to specify a start node where the tracing begins.
   • Click Visit/End Features to specify an end node for the shortest path analysis.
7. When you finish, click Trace.

   The resulting features are highlighted in the map and listed in the Tracing Result dialog box.

8. Expand the items, select a feature, and do any of the following:
   • Select an item and click .

     All features under the selected item are highlighted. To remove the highlighting, click .

   • Zoom to the highlighted feature in your map. You can also click Zoom On Click to automatically zoom to a feature when you click it.
   • Open the feature class form to see feature information.
   • Delete the selected feature from the database.

To create a stop condition

1. In the Workflows pane, under Stop Condition Editor, click Add to add a stop condition.
2. Click New. Enter a name.

   If you do not enter a name, the stop condition is used for the current process but is not stored for later use.

3. In the Stop Condition Editor dialog box, select a feature class.
4. Select an attribute in that feature class.
5. Enter a value for the attribute. Note that there is no blank space between the value and the operator.

   If the network trace finds a feature of the selected feature class with the specified attribute, the network trace stops at that feature.

6. Click OK to save the stop condition.

In the Stop Condition Editor dialog box, the list displays only the stop conditions that are not assigned to any tracing template.

To edit a stop condition in the Stop Condition Editor

Note that the Stop Condition Editor list box displays only the stop conditions that are not assigned to any tracing template.

• You can only edit the stop conditions that you have created while executing a workflow.
• You cannot edit stop conditions that other users have created while executing a workflow.
• You cannot edit stop conditions that have been created using Infrastructure Administrator, or that have been created by the system.
