SysML2Workbench

A cross-platform desktop viewer and GUI custom-view builder for SysML v2 models, built on the SysML2Tools rendering engine.

SysML2Workbench opens a folder of .sysml files as a live workspace, renders the same predefined diagrams (General, Interconnection, State Transition, Action Flow, Sequence, and Grid) produced by the SysML2Tools CLI in an interactive pan/zoom viewer, and lets you build ad-hoc custom views through a GUI - picking a view kind, multi-selecting target elements, and optionally filtering - without hand-writing SysML view syntax. Custom views can be exported as copy-pasteable SysML view ... expose ... text to promote them into a permanent model file. A live-updating diagnostics panel surfaces parser and reference-resolution problems across the whole workspace, and a local rolling log file is written for bug-report attachments.

This is a Phase 0, read-only release: there is no git integration, no text/structural editing, no telemetry, and custom views are session-only until exported as text. See architecture.md for the full scope and docs/user_guide/ for usage instructions.

Getting Started

Requires the .NET 9 SDK.

dotnet run --project src/DemaConsulting.SysML2Workbench.Desktop

See docs/user_guide/getting_started.md for a walkthrough of opening a workspace, browsing predefined views, and building a custom view.

Repository Layout

• src/DemaConsulting.SysML2Workbench/ - shared application project (all subsystems: workspace, view catalog, view builder, layout/rendering, diagnostics panel, logging, app shell).
• src/DemaConsulting.SysML2Workbench.Desktop/ - desktop platform head (Windows/Linux/macOS entry point).
• test/DemaConsulting.SysML2Workbench.Tests/ - unit and subsystem-level tests mirroring src/.
• test/OtsSoftwareTests/ - integration tests for the off-the-shelf (OTS) dependencies (SysML2Tools, Rendering, Avalonia, xUnit).
• docs/ - requirements (docs/reqstream/), design (docs/design/), verification (docs/verification/), the SysML2 architecture model (docs/sysml2/), and the user guide.
• architecture.md - the authoritative Phase 0 scope and technology decisions.
