Create Diagram Layer Definition (Network Diagram)

Summary

Creates a diagram layer definition for the input diagram template using the settings of the network feature layers in the active map.

This tool allows you to do the following:

• Import the appearance and labeling settings configured on each feature layer in the active map when those layers are related to the utility network or trace network specified in the input.
• Create a set of extra layers that may be relevant to your template, such as layers for system junctions, structural attachments, and so on.

Caution:

This tool is a configuration and administration tool.

Usage

• This tool is not supported when working with a utility network or trace network service. You must use either a utility network or trace network in a file or mobile geodatabase, or a database connection to a utility network or trace network in an enterprise geodatabase. When working with an enterprise geodatabase, the following are requirements:

  • The Input Network parameter value must be from a database connection established as the database utility network owner or database trace network owner.
  • The connected ArcGIS Enterprise portal account must be the portal utility network owner or portal trace network owner.
  • This tool must be connected to the default version, which is expected to be public and not protected.

• This tool must be used in ArcGIS Pro, as it takes an input network layer referenced from an active map and prepares the network diagram composite layer for all diagrams that are based on the input template according to the layers in the input active map. After running with its default settings, each network diagram based on the input template displays the following:

  • One layer for each utility network or trace network layer representing network features or network objects in the active map specified as the input.
  • A set of extra layers that can be relevant or not to your template dedicated to the representation of the following types of network elements:
    • Connectivity associations and structural attachments represented as polylines in diagrams
    • Container polygon features, line features, and edge objects that can be transformed as points in diagrams
    • Container point features and container junction objects that can be transformed as polygons in diagrams
    • Junction objects represented as points in diagrams
    • Edge objects represented as polylines in diagrams
  • One layer, Reduction Edges, dedicated to the representation of aggregated network elements between two junctions.

• Depending on the Overwrite all layers parameter value, you can do the following:

  • Initialize a custom diagram layer definition on a template. This is the default behavior when the Overwrite all layers parameter is checked.
  • Add new diagram sublayers or overwrite settings on some existing diagram sublayers while preserving others when the Overwrite all layers parameter is unchecked.
  Then you can refine the diagram layer definition on a template.
