KNOWLEDGE BASE // SYSML PRIMER
SysML is the graphical language of MBSE. It describes a system through four pillars — structure, behavior, requirements, and parametrics — using nine diagram types.
Block Definition and Internal Block diagrams describe the system's components, properties, and how they connect.
Activity, Sequence, State Machine, and Use Case diagrams capture function, interaction, and lifecycle behavior.
Requirement diagrams trace every 'shall' statement to the design elements that satisfy and verify it.
Parametric diagrams bind system properties to engineering equations for analysis and trade studies.

In the SET Academy curriculum, you'll work hands-on with every one of these diagram types — starting with structure and requirements in Systems Modeling I, and building to full parametric analysis and simulation by Systems Modeling III.
