The Sequence Diagram Editor is used to show the dynamic structure of your code, represented as UML Sequence Diagrams.

The Round-trip Engineering process described in the section "Round-trip Engineering", works the same with the Sequence Diagram Editor. Changes to source code are automatically updated in the diagrams.

Sequence Diagrams are organized by package, including the Model. You may create as many Sequence Diagrams as you want per package.

To learn how to customize how Sequence Diagrams are displayed go the Settings section.

Creating New Sequence Diagrams

To create a new Sequence Diagram:

1. Select the desired operation in the Model Explorer or Project View.
2. Either:
   • invoke Edit | New | Sequence Diagram.
     or
   • right-click on the selection and invoke New | Sequence Diagram from the pop up menu.
     
     or
   • press Alt + Insert
     
     and invoke Sequence Diagram.
3. Enter a name for the new Sequence Diagram.
   
4. Confirm the new Sequence Diagram creation by pressing OK and the new generated Sequence Diagram will show up in the editor.
   

Alternatively, you may generate a Sequence Diagram from the source code editor:

1. Move the caret anywhere within the desired method's code.
2. Press Alt + Insert
   
   and invoke Sequence Diagram

Deleting a Sequence Diagram

To delete an existing Sequence Diagram:

1. Select the desired Sequence Diagram(s) in the Model Explorer.
2. Either:
   • invoke Edit | Delete.
     or
   • right-click on the selection and invoke Delete from the pop up menu.
     
     or
   • press Delete.
3. Confirm the Sequence Diagram(s) deletion.
   

Opening a Sequence Diagram

To open a Sequence Diagram in the editor, either double-click with the mouse on the desired Sequence Diagram node, or select the Sequence Diagram in the Model Explorer and then press Ctrl + Enter.
