Add Smart Tree Layout (Network Diagram)

Summary

Adds the Smart 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 Smart Tree Layout algorithm parameters for any diagram based on that template.

This layout algorithm arranges the diagram features hierarchically and places them in a smart tree according to the direction and spacing distances specified. By default, the tree branches are ordered according to their relative positions to each other that they have before the layout applies. Starting with ArcGIS Pro 3.6 and ArcGIS Enterprise 12.0, the tree branches can also be ordered according to attribute values on the branches; that is, according to an attribute existing on the lines or on the extremity junctions of the branches.

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.

• To preset the layout algorithm parameters for a diagram based on the diagram template, uncheck the Active parameter (is_active = "INACTIVE" in Python).

• Run the tool with Active checked (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.

Unchecked—The layout algorithm will apply to both content and noncontent features in the diagram. This is the default.	Boolean

From right to left—The tree will be drawn from right to left. From bottom to top—The tree will be drawn from bottom to top. From top to bottom—The tree will be drawn from top to bottom.	String
Spacing values interpreted as absolute units in the diagram coordinate system (Optional)	Specifies how parameters representing distances will be interpreted. Checked—The layout algorithm will interpret distance values as linear units. Unchecked—The layout algorithm will interpret distance values as relative units to an estimation of the average of the junction sizes in the current diagram extent. This is the default.	Boolean
Between Subtrees (Optional)	The spacing that will be used between two neighboring subtrees—that is, the spacing between diagram junctions that are displayed perpendicular to the smart tree direction and belong to a different subtree. The default is in the units of the diagram's coordinate system. This parameter can only be used with absolute units.	Linear Unit
Between Subtrees (Optional)	The spacing that will be used between two neighboring subtrees—that is, the spacing between diagram junctions that are displayed perpendicular to the smart tree direction and belong to a different subtree. The default is 2. This parameter can only be used with proportional units.	Double

It is a percentage between 0 and 100. With a Break Point Relative Position (%) value of 0, the break point is positioned at the x-coordinate of the edge's from junction and at the y-coordinate of the edge's to junction for a horizontal tree. It is positioned at the y-coordinate of the edge's from junction and at the x-coordinate of the edge's to junction for a vertical tree. With a Break Point Relative Position (%) value of 100, there is no break point inserted on the diagram edges; each diagram edge directly connects its from and to junctions. With a Break Point Relative Position (%) value of N between 0 and 100, the break point is positioned at N% of the length of the [XY] segment, X being the x-coordinate of the edge's from junction and Y being the y-coordinate of the edge's to junction for a horizontal tree. It is positioned at N% of the length of the [YX] segment, Y being the y-coordinate of the edge's from junction and X being the x-coordinate of the edge's to junction for a vertical tree. The relative position of the two inflection points that will be inserted along the diagram edges to compute the curved edges geometry when Edge Display Type is set to Curved edges (edge_display_type = "CURVED_EDGES" in Python). It is a percentage between 15 and 40. With a Break Point Relative Position (%) value of N between 15 and 40: X being the x-coordinate of the edge's from junction and Y being the y-coordinate of the edge's to junction for a horizontal tree: The first inflection point will be positioned at N% of the length of the [XY] segment. The second inflection point will be positioned at (100 - N)% of the length of the [XY] segment. Y being the y-coordinate of the edge's from junction and X being the x-coordinate of the edge's to junction for a vertical tree: The first inflection point will be positioned at N% of the length of the [YX] segment. The second inflection point will be positioned at (100 - N)% of the length of the [XY] segment. Note: The concept of the from and to junctions above is relative to the tree direction; it has nothing to do with the real topology of the edge feature or edge object in the network.	Double

Attribute Availability (Optional)	Specifies whether the attribute to consider is available on diagram junctions or diagram edges. Search the attribute on junctions—The attribute to consider is available on diagram junctions. This is the default. Search the attribute on edges—The attribute to consider is available on diagram edges.	String

When the Attribute Availability parameter value is Search the attribute on junctions, this order attribute will be queried on the branch extremity junctions. When the Attribute Availability parameter value is Search the attribute on edges, this order attribute will be queried on the branch extremity edges.	String
Attribute Sort Order (Optional)	The sort order that will be used for positioning the branches of the tree layout. Sorting always applies from the first branch on the left to the last branch on the right for vertical tree layouts, that is, when the Tree Direction parameter value is From top to bottom or From bottom to top. For horizontal tree layouts, sorting applies from the first branch at the top to the last branch at the bottom, that is, when the Tree Direction parameter value is From left to right or From right to left.
