About SysMLv2 Editor is a Visual Studio Code extension from Change Vision, Inc. for writing SysML v2 models in the standard textual notation. Models are saved as plain-text .sysml files in your VS Code workspace. Features include syntax highlighting, real-time detection of syntax and spelling errors, jump to definition and reference navigation, an outline view for a structural overview, and automatic diagram generation from the text. SysMLv2 Editor runs on Windows, macOS, and Linux. It is included at no extra cost with a valid Astah SysML, Astah System Safety, or Astah Faculty Site License, and it stays available while that license is valid. A 20-day free trial is available. It is not data-compatible with Astah products, so it does not open SysML v1 models created in Astah SysML.
