Creating master-slave relationships

Hierarchical relationships have designated master and slave features. A master-slave relationship is created to relate features comprising a navigational aid. Navigational aids are composed of two basic types of objects: structures and equipment. The structure object is considered the master feature, and all the related equipment the slave features. A lighted buoy is a good example of a master-slave relationship. The buoy is a master structure with different equipment attached to it, such as lights and navigational devices, which are considered slave features.

To create a master-slave relationship between two points, the two point features must share the same x,y geometry values. However, when line, area, and point geometry type features are grouped into a master-slave relationship, they do not have to share similar geometry values. There could be more than one slave feature, but only one master feature is allowed in a relationship. If you have selected two or more master features when creating a master-slave relationship, you have to choose which one is the master feature from the selection, and the remaining master features become slave features in the relationship.
