Working with sub-activity diagrams

Opening a sub-activity diagram

You can open the sub-activity diagram of a decomposed activity in any of the following ways:

Press ctrl and double-click on the decomposed activity symbol
Right-click the diagram background and select Diagram→Go Up One Level from the contextual menu. If several diagrams are open in the workspace, you are requested to select the desired diagram.
Double-click the appropriate diagram entry in the Browser

You can move from a sub-activity diagram to another diagram in any of the following ways:

Press ctrl + u to go to the model's default diagram
Right-click the activity and select Open Diagram from the contextual menu
Double-click the sub-activity diagram entry under the decomposed activity in the Browser

Setting a diagram as default diagram
You can set a diagram to be the model's default diagram by selecting the Default Diagram check box in its property sheet, or by selecting the diagram in the Default Diagram list in the model property sheet.

Adding objects to a sub-activity diagram

You can add objects to a sub-activity diagram in the same way as you add them to an activity diagram. Any activities that you add to a sub-activity diagram will be a part of its parent decomposed activity and will be listed under the decomposed activity in the Browser.

Find in Browser
You can locate any object or any diagram in the Browser tree view from the current diagram window. To do so, right-click the object symbol, or the diagram background and select Edit→Find in Browser.

Composite view

You can change a decomposed activity symbol to give a representation of its sub-activity diagram. To do so, right-click a decomposed activity and select Composite View from the contextual menu. You may need to resize the symbol to see all its content.

For more information, see the "Expanding the symbol of a decomposed object" in the "Model Graphics" chapter in the General Features Guide.
