  1. Open Unzip the MagicDraw model (UAV_Graph.mdzip) or the Rhapsody model (zip file and open the model UAV_Graph.rpy inside the UAV_Graph.zip) included in the Syndeia MagicDraw Plugin and Example folder or the Syndeia Rhapsody Plugin and Example folder in the deliverable packagefile in Rhapsody.

  2. The System package in the model includes sub-packages named Activity, Interactions, Requirements, State Machines, Stereotypes, Structure, and Use Cases, as shown in Figure 4 (MagicDraw) and Figure 5 (Rhapsody)the figure below. The UAV structure is shown as a SysML BDD in the figure. As the name suggests, the packages include behavior, structure, and requirement representations of an example UAV system. The elements in these representations are interconnected, as you will see when you run the queries in the next section.
