Summary
Adds the Radial Tree Layout algorithm to the list of layouts to be automatically chained at the end of the building of diagrams based on a given template. This tool also presets the Radial Tree Layout algorithm parameters for any diagram based on that template.
This layout algorithm arranges the diagram features hierarchically and places them in a radial tree according to the specified radius parameters. It works from a root junction that it uses as the circle center to arrange the subtrees starting from this root in concentric circles, each circle corresponding to one hierarchical level.

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 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.
To preset the layout algorithm parameters for any diagram based on the diagram template, uncheck the Active parameter (is_active = "INACTIVE" in Python).
Run the tool with Active checked (the default) (is_active = "ACTIVE" in Python) if you want the layout algorithm to be added to the list of layouts that will be automatically chained at the end of diagram generation based on the input diagram template.
Syntax
arcpy.nd.AddRadialTreeLayout(in_utility_network, template_name, is_active, {are_containers_preserved}, {is_unit_absolute}, {initial_radius_absolute}, {initial_radius_proportional}, {disjoined_graph_absolute}, {disjoined_graph_proportional}, {radius_factor})| Parameter | Explanation | Data Type |
in_utility_network | The utility network or trace network containing the diagram template to modify. | Utility Network; Trace Network |
template_name | The name of the diagram template to modify. | String |
is_active | Specifies whether the layout algorithm will automatically execute when generating diagrams based on the specified template.
| Boolean |
are_containers_preserved (Optional) | Specifies how the algorithm will process containers.
| Boolean |
is_unit_absolute (Optional) | Specifies how parameters representing distances will be interpreted.
| Boolean |
initial_radius_absolute (Optional) | The radius of the first concentric circle whose center is the radial tree root junction—that is, the radius of the circle around which the diagram junctions belonging to the first hierarchical level are placed. The default is 5 in the units of the diagram's coordinate system. This parameter can only be used with absolute units. | Linear Unit |
initial_radius_proportional (Optional) | The radius of the first concentric circle whose center is the radial tree root junction—that is, the radius of the circle around which the diagram junctions belonging to the first hierarchical level are placed. The default is 5. This parameter can only be used with proportional units. | Double |
disjoined_graph_absolute (Optional) | The minimum spacing that will separate features belonging to disjoined graphs when the diagram contains such graphs. This parameter is used with absolute units. The default is 4 in the units of the diagram's coordinate system. | Linear Unit |
disjoined_graph_proportional (Optional) | The minimum spacing that will separate features belonging to disjoined graphs when the diagram contains such graphs. This parameter is used with proportional units. The default is 4. | Double |
radius_factor (Optional) | The multiplicative factor used to increase or decrease the radius of each concentric circle. It is also the distance that separates each concentric circle related to a hierarchical level. When using a radius factor less than 1, the distance that separates the diagram junctions belonging to the (n) hierarchical level and the (n+1) hierarchical level progressively decreases. With a factor greater than 1, the distance between the hierarchical levels increases progressively. The default is 1. | Double |
Derived Output
| Name | Explanation | Data Type |
| out_utility_network | The updated utility network or trace network. | Utility Network; Trace Network |
| out_template_name | The name of the diagram template. | String |
