Create a hierarchical relationship between features at the same location. One feature is designated the master, others are its slaves. For example, a buoy could be a master and attached equipment such as lights and navigational devices would be its slaves. Relationships can be created between any feature object types in an open data source.
Once created, relationships can be viewed through either the Relations window or using the Select Relationships command. The Relations window is not included in the interface by default, it must be added using the View > Windows command. This window displays the relationship of a superselected feature, if it is part of a relationship. When a feature is populated in the Relations window, you can right-click that feature and select the View Relationships command to launch the Select Master/Slave Relationships dialog box. The Select Relationships command also launches the Select Master/Slave dialog box. This dialog box is used to view the features in a relationship and their attributes. Refer to the documentation under Related commands for more information on this dialog box.
The Edit Relationships command can be used to edit master/slave relationships after they have been created. Refer to the documentation for this command for more information.

Procedure: Automatic
Menu | Create > Relationships > Automatic |
Automatically create relationships from a selection of features in the same location based on the attributes of the objects in the catalogue of the data source. The catalogue specifies whether an object is a master or a slave feature and which master features a slave feature is associated with.
The master/slave designations in a catalogue can be changed if needed. Edits to a catalogue are performed in the Catalogue Editor application. If the data source is a database, such as a BDB Server database, additional steps are required. For information on updating database catalogues, refer to Edit Relationships in a Database.
1. Select one or more features to use in the relationship.
2. Select the Automatic Relationships command.
The relationships are created.
Messages are displayed in the Output window reporting the number of new relationships created and any errors that may have occurred.
Procedure: Manual
Menu | Create > Relationships > Manual |
Manually create a relationship between any superselected and selected features.
Some data sources, such as databases in BDB Server, do not allow relationships to be created manually. for example . This command is not available for objects in a BDB Server database; relationships can only be created for these objects using the Automatic method. |
The manual selection of features overrides the master/slave relationships set by the catalogue. Any selected feature can become a slave of any superselected master.
1. Select one or more features.
2. Superselect the feature to use as the master.
3. Select the Manual Relationships command.
If the superselected feature is not a recognized master object in the catalogue, a warning message is displayed.
