Geo - Angle Directed layout algorithm properties

When the Geo - Angle Directed 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 either those specified by default by ArcGIS Schematics or those specifically set as the default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layout Task tab for this schematic diagram template.

Number of Iterations parameter

The Number of Iterations parameter value determines the number of Geo - Angle Directed algorithm iterations that are executed before the final result is shown.

The figures below show the results obtained for the same schematic diagram with different values for the Number of Iterations parameter:

The same direction option (8 directions) was checked for each result.

Direction options

The direction options specify the number of directions that can be used to align the schematic links.

The figures below show the impact of the direction options:

The results in figures 2.2, 2.3, and 2.4 were all obtained after 80 iterations.

Restore Defaults button

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