SysML v2 Diagram Coverage

Modeler CLI V0.10.3+, against the OMG SysML v2 specification (SysML 2.0, release 2026-04).

Syside Modeler CLI renders diagrams directly from SysML v2 textual models. The tables below list its coverage of the standard graphical notation, domain by domain.

Note

This page covers the diagram engine used by syside viz in Modeler CLI. The interactive diagram viewer inside VS Code, powered by Tom Sawyer Software, is a separate component and is documented in Diagram Visualization.

Graphical Notation

Each element is marked with one of four statuses:

  • Supported - fully implemented

  • Partial - partially implemented

  • Planned - on the roadmap

  • Out of scope - no current plans
