Access a variety of diagram connectors to build any UML relationship your system requires. Try out the Class stencil along with the Package, Note, or Interface stencils. Our template integrates specific UML stencils you can easily use to either create sequence diagrams or to incorporate them in other types of diagrams. Having access to all the tools required for building a UML sequence diagram is mandatory. Working with a sequence diagram template in Moqups Comments - UML diagrams allow the use of comments across multiple templates, sequence diagram included.Messages - every message is represented by an arrow and is located between the lifelines of two objects.Activation bars - are empty boxes placed below the lifelines that represent the time it takes for an object to complete a task.Lifelines - are box-shaped elements located at the top of the diagram that can represent object instances or roles that play a role in the sequence.Actors - can be represented by a user or another entity that may be interacting with the system.Our UML sequence diagram template comes with a set of standard notations that must be known by all users.
