STK Object Hierarchy

The following table displays the parent-child relationships possible between all STK objects. Certain objects require specific licensing, but to make the table simpler to read this information has been excluded from it.

All of the objects are listed in the table with their hierarchy relationships indicated across the row. The Independent column indicates whether the object can exist by itself at the scenario level. The Parent column indicates if the object is capable of having child objects assigned to it, while the Child column indicates if the object is capable of being a child of another object. Finally, the Valid Children column lists the objects that the object can be a parent to, if the object is capable of having children assigned to it.
