Hierarchical - Compact Tree layout algorithm properties

When the Hierarchical - Compact Tree schematic layout algorithm is chosen in 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:

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

About root schematic node

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

Direction options

The Direction options determine the direction of the compact tree.

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 schematic nodes belonging to a given hierarchical level will be computed. The unit for these spacing 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 units relative to the average of the current symbol sizes used to represent the schematic nodes in the diagram. In this case, when the Between nodes along the direction parameter value is 2, the distance that separates two schematic 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 Compact Tree parameters to their default values. The restored values are those either specified by default by Schematics or specifically set as the default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layouts tab for this schematic diagram template.
