About SysMLv2 Editor
SysMLv2 Editor is a Visual Studio Code extension for writing SysML v2 models in the textual notation, developed by Change Vision, Inc. Models are plain .sysml files, so they can be tracked in Git, compared in pull requests, and reviewed alongside source code.
Features include syntax highlighting, real-time validation against the SysML v2 grammar, navigate to definition, an outline view, and diagram generation for reviewing structure and behavior. Diagrams are read-only; editing happens in the text. For editing directly on diagrams, Change Vision offers SysMLv2 Modeler (early access).
SysMLv2 Editor runs on Windows, macOS, and Linux. It is included with an Astah SysML, Astah System Safety, or Astah Faculty Site License, with no separate purchase, and a 20-day free trial is available. It does not import SysML v1 models from Astah SysML.
