Manage white space editing in a network diagram

You can adjust the spacing between diagram features at any time by editing and reshaping the features. White space editing in network diagrams is limited to the reshape of diagram features, that is, moving diagram features and editing vertices along diagram edges.

Editing a diagram feature automatically edits other visible diagram features topologically connected or related to it. For example, moving a diagram junction stretches all connected diagram edges. Moving a diagram polygon container moves all its contents at the same time.

Requirements and prerequisites

The following requirement must be met when editing features in a network diagram:

• This operation applies to a network diagram layer that is from either a utility network or trace network in a file geodatabase, or a network diagram service. When working with a utility network or trace network in an enterprise geodatabase, the input network diagram layer must be from a service.

How to edit and reshape network diagram features

To edit and reshape features in a network diagram, complete the following steps:

1. Activate the network diagram you want to edit. Do one of the following depending on whether the diagram is currently open:
   • For a stored diagram that is not already open, run the Find Diagrams tool on the Network Diagram tab or on the Data tab under the utility network or trace network tab set to find and open the diagram you want to work with.
   • For a diagram that is already open, click a map view that references the diagram. If the map view is not related to a diagram map or is related to a diagram map that references several network diagrams, click the network diagram layer in the Contents pane.
2. Use the Move tool to move a diagram feature as follows:
   1. Zoom in to the diagram feature you want to move.
   2. On the Edit tab, click the Move tool and click the diagram feature you want to move.

      The editing toolbar appears with construction tools:

      

   3. On this toolbar, click Stretch Topology to disable proportional topology stretching.

      Editing while preserving relative shapes is generally not the expected behavior when working on a network diagram.

   4. Drag the selected diagram feature to the desired location.
   5. Click Finish on the Editing toolbar.

   • Moving a diagram junction stretches all connected diagram edges.
   • Moving a diagram edge moves its from and to diagram junctions and stretches the diagram edges that connect them.
   • Moving a diagram polygon container moves all the related containers.
   • Moving any content diagram feature causes the related container to be redrawn around all its contents.

3. Use the Vertices tool to edit vertices along diagram edges as follows:
   1. On the Edit tab, click the Vertices tool .

      The Modify Features pane appears.

   2. Select the diagram edge you want to edit.
   3. Drag any vertex to the desired location.
   4. To add a new vertex, click the Add Vertex tool on the vertices toolbar and click the diagram edge at the location where you want to insert the new vertex.
   5. To delete an existing vertex, click the Delete Vertex tool on the vertices toolbar and click the vertex you want to delete.
   6. Click Finish on the vertices toolbar.

   It is possible to edit vertices along diagram polygon containers. However, any diagram update will systematically recompute the diagram polygon container geometry so it displays as a rectangle around all its related contents.

Tip:

The diagram extent is not recomputed on-the-fly after manual editing operations. This means that if you move diagram features out of the diagram extent, and then click Full Extent or Zoom to Layer from the diagram layer, the moved features may not fit the diagram map extent. To get the diagram extent updated after manual editing operations, click Recalculate Diagram Extent on the Modify group of the Network Diagram tab.
