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

UML Designer offers a set common diagrams that can be used with UML 2.5 models. This is a simple way to transition from UML to domain-specific modeling. Users can use the provided representations to continue working with legacy UML models, and then switch to DSL. You can also reuse the representations provided and have total transparency on both UML models and DSL models. It is a general workbench for model-based architectural engineering and can be easily customized to meet specific needs. It uses the Eclipse Foundation's standard UML2 metamodel. It is based upon Sirius and allows for easy integration of UML and domain-specific modeling. You can easily extend the diagram definitions to work seamlessly on both UML models and DSL models simultaneously. It is easy to modify each diagram to suit your needs. Try the latest UML Designer release to get the code.
