SysML Plugin TWRT Documentation

The correct organization of your diagrams in the model ensures model consistency, reusability of required views, and quick navigation in the model. In the following sections you can learn about:

SysML diagram taxonomy

The figure below shows the SysML diagram taxonomy, which reflects how SysML diagrams are organized. You can use nine kinds of SysML diagrams when modeling:

The relationship between SysML diagrams is Generalization:

  • Activity, Sequence, State Machine, and Use Case diagrams are types of behavior diagrams. 
  • Block Definition, Internal Block, and Package diagrams are types of structure diagrams.
  • Parametric diagrams are types of Internal Block diagrams.
  • Requirement diagrams are a category by themselves.

Diagram owners

The owner that a diagram can represent depends on the diagram kind you are creating. All SysML diagrams and their available owners are listed in the following table.

A Behavior diagram must have a context which is always a behavior which owns this diagram.

SysML DiagramOwner
Requirement DiagramPackage, Model, Requirement
SysML Block Definition DiagramPackage, Model, Block, Constraint Block
SysML Internal Block DiagramBlock
SysML Parametric DiagramBlock
SysML Package DiagramPackage, Model, Profile
SysML Activity DiagramActivity
SysML Sequence DiagramInteraction
SysML State Machine DiagramState Machine
SysML Use Case DiagramPackage, Model


Find diagrams in your project

You can find all diagrams of your model by using the Diagrams tab in the Model Browser. The Diagrams tab page describes how to open and use this tab.
