Add Mainline Tree Layout (Network Diagram)

Summary

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

This layout algorithm arranges the junctions and edges in the input network diagram hierarchically along a main line and places its related branches on the left side, the right side, or both sides of the main line.

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.

arcpy.nd.AddMainlineTreeLayout(in_utility_network, template_name, is_active, {are_containers_preserved}, {tree_direction}, {branches_placement}, {is_unit_absolute}, {perpendicular_absolute}, {perpendicular_proportional}, {along_absolute}, {along_proportional}, {disjoined_graph_absolute}, {disjoined_graph_proportional}, {are_edges_orthogonal}, {breakpoint_position}, {edge_display_type}, {offset_absolute}, {offset_proportional})

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. ACTIVE —The added layout algorithm will automatically run during the generation of any diagram that is based on the template_name parameter. This is the default.The parameter values specified for the layout algorithm are used to run the layout during diagram generation. They are also loaded by default when the algorithm is to be run on any diagram based on the input template. INACTIVE —All the parameter values currently specified for the added layout algorithm will be loaded by default when the algorithm is to be run on any diagram based on the input template.	Boolean
are_containers_preserved (Optional)	Specifies how the algorithm will process containers. PRESERVE_CONTAINERS — The layout algorithm will execute on the top graph of the diagram so containers are preserved. IGNORE_CONTAINERS —The layout algorithm will execute on both content and noncontent features in the diagram. This is the default.	Boolean
tree_direction (Optional)	Specifies the direction of the main line. FROM_LEFT_TO_RIGHT —The main line will be drawn as a horizontal line starting from the left and ending on the right. This is the default. FROM_RIGHT_TO_LEFT —The main line will be drawn as a horizontal line starting from the right and ending on the left. FROM_BOTTOM_TO_TOP —The main line will be drawn as a vertical line starting from the bottom and ending at the top. FROM_TOP_TO_BOTTOM —The main line will be drawn as a vertical line starting from the top and ending at the bottom.	String
branches_placement (Optional)	Specifies how branches from the main line will be relatively placed with regard to its direction. BOTH_SIDES —Branches will be placed on both the left and right sides of the main line. This is the default. LEFT_SIDE —Branches will only be placed on the left side of the main line. RIGHT_SIDE —Branches will only be placed on the right side of the main line.	String
is_unit_absolute (Optional)	Specifies how parameters representing distances will be interpreted. ABSOLUTE_UNIT —The layout algorithm will interpret any distance values as linear units. PROPORTIONAL_UNIT —The layout algorithm will interpret any 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
perpendicular_absolute (Optional)	The spacing between diagram junctions that are displayed along the axis perpendicular to the main line. The default is 2 in the diagram's coordinate system. This parameter can only be used with absolute units.	Linear Unit
perpendicular_proportional (Optional)	The spacing between diagram junctions that are displayed along the axis perpendicular to the main line. The default is 2. This parameter can only be used with proportional units.	Double
along_absolute (Optional)	The spacing between diagram junctions that are displayed along the main line, as well as the spacing between diagram junctions that are displayed along the axis parallel to the main line. This parameter can only be used with absolute units. The default is 2 in the units of the diagram's coordinate system.	Linear Unit
along_proportional (Optional)	The spacing between diagram junctions that are displayed along the main line, as well as the spacing between diagram junctions that are displayed along the axis parallel to the main line. This parameter is used with proportional units. The default is 2.	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
are_edges_orthogonal (Optional)	Specifies how diagram edges that are related to the tree branches will display. Legacy: This parameter is deprecated at ArcGIS Pro 2.7. It is systematically ignored regardless of its value when the edge_display_type parameter is specified. However, to maintain compatibility with ArcGIS Pro 2.1, it remains enabled when the edge_display_type parameter is not specified. ORTHOGONAL_EDGES —All diagram edges related to the tree branches will display with right angles. SLANTED_EDGES —All diagram edges related to the tree branches will not display with right angles. This is the default.	Boolean
breakpoint_position (Optional)	The relative position of the break point that will be inserted along the diagram edges when Edge Display Type is Regular edges (edge_display_type = "REGULAR_EDGES" in Python) or Edge Display Type is Orthogonal edges (edge_display_type = "ORTHOGONAL_EDGES" in Python). 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 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
edge_display_type (Optional)	Specifies the type of display for the diagram edges related to the tree branches. REGULAR_EDGES —All diagram edges related to the tree branches will not display with right angles. This is the default. ORTHOGONAL_EDGES —All diagram edges related to the tree branches will display with right angles. CURVED_EDGES —All diagram edges related to the tree branches will be curved.	String
offset_absolute (Optional)	The offset used to separate overlapping segments when is_unit_absolute = "ABSOLUTE_UNIT" and edge_display_type = "ORTHOGONAL_EDGES". The value cannot exceed 10 percent of the smallest value specified for the other spacing parameters. The default is 0.	Linear Unit
offset_proportional (Optional)	The offset used to separate overlapping segments when is_unit_absolute = "PROPORTIONAL_UNIT" and edge_display_type = "ORTHOGONAL_EDGES". It is a double value that cannot exceed 10 percent of the smallest value specified for the other spacing parameters. The default is 0.	Double
