The topic is focused on two options that have a great impact on user workflows, found in the General section on the Network Diagram tab in the Network Options dialog box:
- Automatically zoom to full extent after any editing operation executed on the entire diagram
- Open diagrams with all diagram template sublayers
To learn about how to access these options, see Access the network diagram options.
Automatically zoom to full extent after any editing operation executed on the entire diagram
This option is considered each time a network diagram editing operation applies to the entire diagram; that is, the system doesn't consider this option when such an operation executes on a set of diagram features currently selected in the diagram:
- Checked—The system zooms to the full extent of the network diagram each time a layout algorithm is applied on the entire diagram or after operations such as update diagram, append to diagram, extend diagram, or overwrite diagram.
- Not checked—The display extent of the network diagram does not change at the end of any layout algorithm execution or after operations such as update diagram, append to diagram, extend diagram, or overwrite diagram.
By default, the option is checked causing the display extent of the active diagram to automatically change at the end of any network diagram editing operation that applies to the entire diagram content.
If you intentionally zoom in on a diagram portion to execute operations for which you want to analyze the impact on that particular diagram portion—for example, extending the diagram or appending network features or network objects to diagram—uncheck this option prior to executing the operation. The diagram map view stays centered on the portion you are focusing on at the end of the operation.
Note:
The Automatically zoom to full extent after any editing operation executed on the entire diagram option only applies to network diagram editing operations; that is, applying layouts to diagrams, extending diagrams, updating diagrams, overwriting diagrams, or appending network elements to diagrams.
It does not apply when editing diagram features using core editing tools—such as edit vertices or move features—because the extent of the diagram itself is not recalculated on-the-fly at the end of such editing tasks. This means that, at the end of a core editing operation sequence, users must manually proceed in two steps:
- Click Recalculate Diagram Extent on the Modify group of the Network Diagram tab to force recalculating the extent of the active network diagram extent.
- Then, click Full Extent on the Navigate group of the Network Diagram tab to force the display extent to fit the diagram extent.
Open diagrams with all diagram template sublayers
This option is considered at any diagram opening whether the open diagram is temporary or stored:
- Checked—The All Layers mode on the Manage group on the Network Diagram tab is turned on for each network diagram layer at its loading by default; that is, any diagram opens with all the sublayers as specified in its diagram template layer definition whether they contain diagram features or not. This means that all sublayers set on the related diagram template are present in the Contents pane, even those not used.
- Not checked—The All Layers mode on the Manage group on the Network Diagram tab is turned off for each network diagram layer at its loading by default; that is, any diagram opens with the only diagram template sublayers that contain diagram features. This means that only the required sublayers among those set on the related diagram template are present in the Contents pane.
By default, the Open diagrams with all diagram template sublayers option is unchecked; that is, any network diagram layer displays with the All Layers mode turned off by default on the Manage group on the Network Diagram tab. Running with this option unchecked allows you to gain performance at any diagram opening, especially when only a few layers are required to display all the diagram features. Use this mode to open diagrams for simple viewing, applying diagram layouts, or white space editing.
| Option status | All Layers mode status at network diagram layer loading |
|---|---|
 |  |
However, check this option prior to working with network diagrams for which you already know that the content is going to be increased or decreased during your workflow, for example, when you are going to work with the Dynamic Diagram mode, or execute commands such as Extend Diagram, Append to Diagram, or Overwrite Diagram to refine your diagram content. You will typically execute these operations when working with diagrams to control network connectivity or explore the network.
| Option status | All Layers mode status at network diagram layer loading |
|---|---|
 |  |
Note:
In all cases, at any time if needed, you can also switch the network diagram layer you are working on to the other mode by clicking the All Layers button on the Manage group on the Network Diagram tab. But be aware that manually turning this mode on or off is time consuming for network diagram layers that are already loaded.
| All Layers turned off (default) | All Layers turned on |
|---|---|
Gain performance at diagram opening | Required before processing operations such as Extend Diagram, Append to Diagram, Overwrite Diagram |
Maximize performance when applying diagram layouts, updating diagrams, white space editing | Required to enable dynamic diagram mode on a temporary diagram |
