How do I visualize full Use Case diagrams (actors + connections) in SysIDE VS Code?

Hi all — I’m trying to visualize a Use Case diagram in the Sys IDE-Modeler (VS Code extension) and I’m not getting actor → use case connections or a system boundary the way I expect.

Source: I’m using the SysML v2 training example here:
https://github.com/Systems-Modeling/SysML-v2-Release/tree/master/sysml/src/training/35.%20Use%20Cases

What I did (repro):

  1. Open the repo in VS Code.

  2. Navigate to the 35. Use Cases example.

  3. Run “Sys IDE- Visualize Current File” on the .sysml file.

What I see: a figure with two use cases (e.g., provide transportation, add fuel) and a «part def» Fuel Station block, but no connectors between the system, the use cases, and the actors (vehicle, fueler, fuel station). (screenshot attached)

What I expected: a standard Use Case diagram showing:

  • actors (vehicle, fueler, fuel station),

  • the subject/system boundary,

  • associations between actors and use cases (and any include/extend relations if present).

Questions

  1. Does Sys IDE-’s visualizer support rendering actor ↔ use case associations and the subject boundary out of the box for this example?

  2. If yes, what am I missing? (specific command, setting, or required annotations/viewpoints?)

  3. If not, is there an example or recommended pattern (e.g., a particular viewpoint or presentation annotation) to produce a classic Use Case view

Environment

  • VS Code: (version 1.104)/ Windows 11

  • Sys IDE-modeler extension: 0.7.2 (from marketplace)

Thanks in advance! If it helps, I can share the exact file I’m visualizing and the output from the visualizer.

Hi Susmitha,

Great question. You’re not missing anything—this is a current limitation of the visualizer, which is still under active development.

While the model is correct, the tool doesn’t yet render the complete Use Case diagram view with all its connections. Support for this is planned for a future release.

Thanks for the valuable feedback!

Best regards,
Simas

Hi,

Is there any update on this from Tom Sawyer?

Hi Zahir,

Use Case diagrams will be available in the upcoming Syside Modeler v0.8.5 release.

Best regards,

Hi @Susmitha_Suresh and @Zahir, Use Case diagram support has been added in Syside Modeler v0.8.5.

See example from SysML-v2-Release training materials below:
