Hierarchical - Smart Tree layout algorithm properties

When the Hierarchical - Smart Tree schematic layout algorithm is chosen from the Layout Task drop-down list, clicking the Layout Algorithm Properties button Layout Algorithm Properties icon on the Schematic Editor toolbar opens its associated properties dialog box as follows:

Smart Tree - properties dialog box

The parameter values are either those specified by default by ArcGIS Schematics or those specifically set as default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layout Task tab for this schematic diagram template.

About root schematic node

The Hierarchical - Smart Tree layout algorithm works from a root schematic node from which the resulting smart tree starts. This root schematic node can be specified using the Set Schematic Root tool Set Schematic Root icon. If no root schematic node is specified, the algorithm automatically considers one of the schematic nodes as the root node.

Direction options

The Direction options determine the direction of a smart tree.

Smart Tree - Directions

Link display parameters

The Link display parameters specify the positioning of vertices that will be added along the schematic links.

Spacing parameters

The Spacing parameters determine how the spacing between the hierarchical levels and the schematic nodes belonging to a given hierarchical level will be computed. The unit for these parameters depends on the Absolute units check box.

Absolute units check box

By default, the spacing parameters are interpreted as absolute units determined by the coordinate system specified on the XY Coordinate System tab of the Schematic Diagram Properties dialog box (Absolute units checked). Uncheck the Absolute units check box if you want these parameter values to be interpreted as relative units to the average of the current symbol sizes used to represent the schematic nodes in the diagram. For example, in this case, when the Between nodes along the direction parameter value is 2, the distance that separates two nodes belonging to the (n) and (n+1) hierarchical levels corresponds to the average size of two symbols placed side by side.

NoteNote:

Specifying parameters in relative units is easier than in absolute units but has real meaning only when there is a reference scale for the diagram.

Restore Defaults button

Click the Restore Defaults button to reset all the Smart Tree parameters to their default values. The restored values are either those specified by default by Schematics or those specifically set as default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layout Task tab for this schematic diagram template.
