The techniques in this section pertain to models of particularly complex composite states and substates.
You can resize the main state. You can also create a substate by drawing a state diagram within another state diagram and indicating start, end, and history states as well as transitions.
Create a composite state by nesting one or more levels of states within one state. You can also place start/end states and a history state inside of a state, and draw transitions among the contained substates.
Using the Shortcuts command on the context menu of the diagram, you can reuse existing elements in other state diagrams. Right-click the diagram and choose Add -> Shortcuts, navigate within the pane containing the tree view of the available project contents for the project group to the existing diagram, and select its elements, states, histories, forks, and/or joins.
