What is UML Designer?

UML Designer provides a variety of standardized diagrams compatible with UML 2.5 models, facilitating a smooth shift from traditional UML to domain-specific modeling. This tool allows users to effectively manage and update legacy UML models before transitioning to DSL, ensuring a seamless workflow. With the ability to reuse existing representations, users can maintain clarity and coherence between UML and DSL models. As a versatile platform for model-based architectural engineering, it offers customization options tailored to individual requirements. Utilizing the Eclipse Foundation's UML2 metamodel, it is built on the Sirius framework, which promotes straightforward integration of UML with domain-specific modeling. Additionally, it allows for the effortless extension of diagram definitions, enabling simultaneous work on both UML and DSL models. Users can easily adapt each diagram to fit their specific needs, ensuring flexibility. Don't miss out on the latest release of UML Designer to access the code and enhance your modeling experience.

What is Astah SysML?

Astah SysML is a desktop SysML v1 modeling application from Change Vision, Inc. for organizations adopting model-based systems engineering (MBSE). It gives engineering teams the core SysML diagrams, including requirement, block, parametric, and behavior diagrams, in a tool that new users can learn quickly. Because designs are stored as models, an update made in one place carries through to every related diagram, which keeps system documentation consistent as a project evolves. Existing models can be exchanged through XMI and with Cameo Systems Modeler. Version 11.0 includes AI Chat Copilot, which runs on your organization's own API key for OpenAI, Azure OpenAI, Claude, or Gemini, or for an OpenAI-compatible service, and local MCP server integration for connecting AI agents. Licensing is available as a 1-year license ($140) or a 1-year floating license ($270). Astah SysML runs on Windows and macOS, and a 20-day free trial is available.
