ASysT Rendering See and navigate your SysML v2 models
ASysT Rendering is a SysML v2 viewer and layouter that lives in VS Code and your
browser. All local. No model modification — only a rendering layer and navigation
on top of your files. It reads your .sysml exactly as it is and never
writes a single character back into your model.
Free to install · Windows (win32-x64) · your files stay on your machine
What ASysT Rendering can do
Two things — arrange your diagrams, then move through the model.
⊞Arrange
A layout pipeline — placement, spacing, orthogonal connection routing, frames — plus named renderings you save per diagram and reopen exactly as you left them. You compose the picture; the model underneath is never touched.
⊕Navigate
Open a model, drill into any part, walk definitions, usages, states and flows with breadcrumbs and Back/Forward — the whole model, across files, package-first.
How ASysT Rendering does it
Local, read-only, nothing to set up.
🔒Your model is never edited
ASysT reads SysML v2 through a language server and writes only its own sidecar files (renderings, sessions, a manifest) next to your model. Diagrams, layouts, colours — all presentation, all separate from your source.
💻Local, no account, no telemetry
Everything runs on your machine. No sign-up, no cloud upload, no tracking. A licence key — when you want one — is a file you drop in a folder.
⚙️Zero-deploy
File-first: install the extension, open a folder with .sysml files, see diagrams. No server to stand up, no project import ceremony.
Real views from a real model
Every figure below was exported by ASysT Rendering itself from its crisis-response pilot model — this is the actual output, not marketing art.
