Add Start Iteration Rule (Network Diagram)

Summary

Adds a diagram rule to specify the beginning of a rule sequence during diagram building based on an existing template.

Learn more about rules that are used to iterate on a particular sequences of diagram rules

Caution:

This tool is a configuration and administration tool.

Note:

This tool impacts the consistency of any existing diagrams based on the input diagram template. All of the existing diagrams become inconsistent and open with a consistency warning icon until they are updated.

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.

• The Start Iteration rule specifies the beginning of a rule sequence on which the diagram builder process will loop. This loop is typically configured when reducing diagram junctions because reduction rules change the number of junctions that connect to the remaining junctions. These connection changes may make some junctions become new candidates for reduction rules that are configured on the template.

Code sample

AddStartIterationRule example (stand-alone example)

Create a template that is configured to trace a subnetwork, remove containers, and loop on a set of reduction rules. The rules will reduce all system and miscellaneous junctions that are connected to 0, 1, or 2 other junctions, reduce all distribution devices except circuit breakers and switches that are connected to 0, 1, or 2 other junctions, and reduce all system and miscellaneous junctions that are connected to 3 or more other junctions.
