UML tool: Sequence diagrams
Examples of UML sequence diagrams with Modelio
UML2 has considerably improved sequence diagrams. It is now possible to reference other UML sequence diagrams, to represent loops and choices, to define formal and current call parameters (gates), and so on.
Modelio sequence diagrams support all these powerful features, and provide a set of smart interactions that make modeling even easier. For example, just drag and drop a class into a sequence diagram to create a lifeline, or drag and drop an interaction into a sequence diagram to create an interaction reference with all its gates.
