Learn when and how to use SysML Activity Diagrams (act) in model-based systems engineering (MBSE)! This tutorial explains how Activity Diagrams fit within SysML, walks through key elements and nodes, and demonstrates real-world examples in Cameo Systems Modeler.
🔹 What You’ll Learn:
✅ Activity Diagrams vs. other SysML diagrams
✅ Key elements: Actions, flows, events, signals, and more
✅ Nesting activities and linking to behavior & structure diagrams
✅ Running scripts & functions with Opaque Actions
✅ Simulating activity flows in Cameo Systems Modeler
