2.2.13. System Navigator

System Navigator is tool for models which has multilevel hierarchy. Database Window always shows the current data storage, System Navigator, on the other hand, it shows full hierarchy of a model. So, you can build a model which need many subsystems and bodies easily. This tree shows not every entity but some main entities like subsystem, body, force and so on.
