You can create your own diagram types for specific domain, platform, technology, or other purposes using the Customize Diagram Wizard. This is a powerful engine that allows creating your own custom elements in diagram toolbar, custom symbol styles, and other customizations.
To open the Customize Diagrams dialog
On the main menu, click Diagrams > Customize.
You can change properties of existing diagrams (Edit function) or create your own brand new diagram type (Create function). Diagram customization descriptors are saved into a separate file for every diagram, so you are able to exchange these customizations with your partners or colleagues (use Import or Export function).
The Reset to default button in Customize Diagrams dialog restores the default configuration for diagrams bundled with MagicDraw installation (it does not work with user-defined diagrams).
To open the Customize Diagram Wizard
In the Customize Diagrams dialog, select a diagram type and click Edit.
Click Create and then select one of the following commands:
Diagram Type, if you need to create a new diagram type.
Dependency Matrix Type, if you need to create a new matrix type.
