Before you code: model the system, not just the syntax
A strong SysML v2 model makes the structure of the system visible. As you work, think about what the system is made of, where interactions happen, and how those parts are connected.
Parts
Use parts to represent the meaningful building blocks of the system you are describing.
Ports
Use ports to show where energy, information, or material enters and leaves a part.
Connections
Use connections to make the relationships between parts explicit and readable.
Tip: if your model clearly answers “what is in the system?” and “how do the parts interact?”, you are already on the right track.
