UML Sequence Diagram. Design Elements
UML Sequence Diagram is a type of Interaction Diagrams that describes the interactions between objects and classes that are involved in the scenario and the sequence of messages exchanged between them.
UML Sequence Diagram represents the processes and objects that occur at the same time as lifelines (parallel vertical lines), and the messages exchanged between them as horizontal arrows.
Sequence Diagrams are very popular in dynamic modeling.
The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.
To design a Sequence Diagram use the UML Sequence Diagram library.
UML Sequence Diagram library contains 51 shapes:
- Lifeline (entity)
- Lifeline (control)
- Lifeline (boundary)
- Lifeline
- Return message
- Asynchronous message
- Synchronous message
- Execution occurrence
- Destroy message
- Create message
- Symbol { }
- Self message
- Symbol << >>
- Port
- State divider
- Stop symbol
- Found message
- State invariant/continuations
- Lost message
- Gate Sequence

When moving to a new apartment it is always pleasure to develop an interior design project. Nevertheless, another important part that should not be forgotten is the piping plan, because wrong piping system might ruin all the renovation. So, to avoid such problems, a stress analysis is performed.
Plumbing and piping plans should be created for any premises. They are used to trace location of pipes, fixtures and valves in the house. This diagram presents a set of certified piping plan symbols for drawing plumbing and piping floor plans, diagrams and other technical drawings. Applying standard symbols when creating a piping plan is very important for creating a valid piping plan included into the building documentation pack. It is essential for any professional to be able to read and properly interpreted any piping plan.
