Description
Astah SysML helps systems engineers capture requirements, structure, and behavior in SysML v1 without the weight of a large enterprise suite. Block definition and internal block diagrams, requirement diagrams and tables, parametric diagrams, and use case, state machine, activity, and sequence diagrams are all included, along with mind maps for early concept work.
Each diagram is a view of one shared model, so updating a requirement or block keeps every related diagram in step. Assist functions such as double-click creation, creating multiple elements from text, and alignment guides reduce drawing time. Models can be exchanged through XMI and with Cameo Systems Modeler, and profiles let teams extend the language.
For AI-assisted work, AI Chat Copilot connects to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key, and a local MCP server lets external AI agents read and work with your models.
Astah SysML runs locally on Windows and macOS. It does not include simulation. Developer: Change Vision, Inc. Current version: 11.0 (March 2026).
Description
The SysMLv2 Editor is an extension for Visual Studio Code that allows users to create SysML v2 models using a textual format, developed by Change Vision, Inc. These models are saved as standard .sysml files, enabling them to be managed in Git repositories, compared in pull requests, and evaluated alongside other source code components.
Among its features are syntax highlighting, real-time validation according to the SysML v2 grammar, the ability to navigate to definitions, an outline view, and the capability to generate diagrams for analyzing both structure and behavior. While diagrams are provided in a read-only format, allowing for text-based editing, Change Vision also offers an early access version of the SysMLv2 Modeler for direct diagram manipulation.
The SysMLv2 Editor is compatible with Windows, macOS, and Linux operating systems. Users can access it through an Astah SysML, Astah System Safety, or Astah Faculty Site License without any additional purchases, and a 20-day free trial is also offered. However, it should be noted that the editor does not support the importation of SysML v1 models from Astah SysML, ensuring a clear distinction between different SysML versions. This focus on SysML v2 could enhance users' experience by providing improved functionalities and a more modern approach to modeling.
