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).
