Subnetwork system diagram and\u00a0 standard diagram definitions<\/h1>\n

Standard diagrams are diagrams that you create and manage on demand starting from the input network features you choose. They represent any part of the network. You can create them for a one-off consultation without storing them in the geodatabase. You can overwrite their content and append new network features to them. You can store a standard diagram as a protected or private diagram to prevent other users from editing or viewing it. You can delete standard diagrams you own and any public diagrams you don’t own at any time.<\/p>\n

A subnetwork system diagram is a publicly stored diagram that represents an entire subnetwork. Its creation and maintenance are fully managed by the system when you update the related subnetwork. You cannot overwrite subnetwork system content, or append new network features to subnetwork system diagrams. Only the portal utility network owner can delete subnetwork system diagrams. You can identify a subnetwork system diagram among all the diagrams created for a utility network. It appears in the Find Diagrams<\/strong> pane with a green exclamation point in the third column of the diagrams list.<\/p>\n

Standard and subnetwork system diagram creation and update<\/h1>\n

Standard diagrams<\/h2>\n

Standard diagram creation<\/h3>\n

To create a standard diagram, you must first select the initial network features or objects you want to use as input, specify the diagram template to apply, and run the Create Diagram<\/a> tool. The Create Diagram tool starts from the input network features and objects and runs in memory applying the sequence of diagram rules configured on this diagram template to progressively build the standard diagram content.<\/p>\n

Standard diagram update<\/h3>\n

To update a standard diagram, you must run another tool, the Update Diagram<\/a> tool. The Update Diagram process automatically retrieves the input network features and objects used as input at diagram creation or at its last update. Then, starting from these queried elements, it reruns the sequence of diagram rules set up on the diagram template to update the in-memory diagram graph. By default, the Update Diagram process preserves the diagram layout. This means that the geometry of the diagram features is kept for any diagram feature present in the diagram before and after the update by default. However, any diagram feature added to the diagram during the update process is placed at its geographical position by default. You can run the Update Diagram tool at any time even when your diagram is not dirty.<\/p>\n

Subnetwork system diagrams<\/h2>\n

Subnetwork system diagram creation<\/h3>\n

Subnetwork system diagrams are created when the Update Subnetwork<\/a> command runs on a subnetwork for the first time and that subnetwork’s tier is configured with a subnetwork diagram template. When no subnetwork diagram template is defined for a tier, no subnetwork system diagram is created when the subnetwork is updated.<\/p>\n

The first time the Update Subnetwork tool runs, the process performs a number of different tasks. It will update the attributes on features that participate in the subnetwork, calculate summaries for the features that participate in the subnetwork, and create a subnetwork line in the SubnetLine feature class. To learn more, read the Update a subnetwork<\/a> page in the online help.
\nNext, if a subnetwork diagram template exists for the related tier, there is an extra step in the process to create a subnetwork system diagram. During this step,\u00a0the subnetwork trace runs in-memory and is used as input to build the related subnetwork system diagram. This diagram build process is the same as any standard diagram build process. It consists of applying the sequence of diagram rules configured on the specified subnetwork diagram template to progressively build the system diagram content.

Subnetwork system diagram update<\/h3>\n

To update a subnetwork system diagram, you must use the Update Subnetwork tool. The update and creation process are the same. The subnetwork system diagram content is fully overwritten starting from the updated subnetwork trace result it builds in memory. The geometry of the diagram features in the updated system diagram is preserved for any diagram feature present in the system diagram before and after the update. However, any diagram features added during the update process are placed at their geographical position.<\/p>\n

Diagram template setting recommendations for system diagrams<\/h1>\n

The diagram templates specified as subnetwork diagram templates for tiers must be considered as specific templates. It is recommended that you design your own subnetwork diagram templates and ensure your template settings obey the following design rules:<\/p>\n
