In a network, assets that provide pathways for a resource, such as water or electricity, are attached to structures such as pads, towers, and poles. In a utility network, this relationship is modeled as a structural attachment association between the attached feature (for example, a transformer) and the structure feature (for example, a pole).
You can use the Modify Associations pane or Python to modify or delete a structural attachment between a structure feature and its attached features.
Use the Modify Associations pane to delete a structural attachment
Follow these steps to modify or delete a structural attachment association between features:
- Click the Utility Network tab.
- In the Association group, click Modify .
The Modify Associations pane is activated.
- In the Modify Associations pane, select the features you want to modify or remove a structural attachment association between.
- Click the Add features tool and click one of the features on the map, for example, a pole, to populate the Active Item parameter in the pane.
Once you've added a feature, it appears in the Modify Associations pane. If there are existing structural attachment associations to other features, they are also displayed.
For nonspatial objects, such as a structure junction object, use the Load selected tool to populate the Active Item in the Modify Associations pane with the selected row from the attribute table.
When the Active Item is populated, the Connectivity, Containment, and Attachment tabs are displayed with an indicator that communicates the number of associations the active item has for each type.
- Click the Attachment tab.
- Click the Add features tool and click one of the features on the map, for example, a pole, to populate the Active Item parameter in the pane.
- Click the delete button next to the feature you want to detach from the structural attachment association under either the Attachments or Attached To sections of the pane.
The section chosen will depend on whether the Active Item is a structure or an attached feature.
Once you've clicked the delete button , the feature is represented in the pane with a strikethrough effect and a green indicator to signify that it will be deleted.
- Click Apply.
The attachment or attachments are removed from the specified structure. Validate the network topology to reflect the change.
Use Python scripting to delete a structural attachment association
Editors can use Python scripting to perform edit operations which include the deletion of structural attachment associations. To do this, you must first import arcpy and start an edit operation to run the DeleteStructuralAttachmentAssociation function.
