UMLmodeller

UMLmodeller is a software tool designed for creating and documenting software systems using the Unified Modeling Language (UML). It provides a visual editor for building diagrams and supports a range of UML diagram types, including class, object, use case, sequence, activity, state machine, and deployment diagrams. The tool is intended to help software engineers, architects, and educators model system structure and behavior, analyze requirements, and communicate designs clearly.

Typical features include a graphical diagram editor with drag-and-drop elements, support for diagram relationships such as associations, generalizations, and dependencies, and tools for arranging layouts. UMLmodeller emphasizes diagram-centric workflows, with options for annotations, templates, and project organization to support collaborative modeling and documentation.

Interoperability and export options focus on common formats used in UML work. Diagrams can be exported to standard image formats, and the tool generally offers import and export capabilities to facilitate exchanges with other modeling tools and workflows.

Platform availability and usage: UMLmodeller is designed to run on multiple operating systems and is used in academic settings, development teams, and enterprise modeling contexts. Depending on the release, it may be distributed as a desktop application or as part of a larger modeling suite.
