Class diagram

Enhanced feature
  • Supported connecting class members

    Attributes and operations of classes can be connected visually with connectors like dependency, generic connectors, etc.

  • Enhanced enumeration literal support in modeling

    Enumeration was supported as attribute in previous versions. In version 11.0, a new enumeration model element type is supported.

  • Supported setting association's default from and to navigability separately

    In previous versions, the default navigability of association from/to ends were determined by a single option. In version 11.0, separate options are provided for setting the default navigability of the from and to ends of association.

Visualize and document model structures with UML class diagram. Construct executable systems with forward, reverse and round-trip engineering. Generate and update entity relationship diagrams from class diagrams via synchronization engine.

Composite structure diagram

Composite structure diagramComposite structure diagram

Visualize the internal structure of a class or collaboration with UML composite structure diagram. Model a system from a micro point-of-view using composite structure diagram, a kind of component diagram.

  • Supported double clicking on slot in instance shape to popup the Slot Specification for editing

    Edit slow in quick by double clicking on a slot in instance specification shape to popup the Slot Specification window.
