Create Diagram Profiles using the Profile Helpers

When you develop an MDG Technology, it is possible to create extended diagram types and include them in your MDG Technology as custom Diagram Profiles. For example, you might create a DFD Diagram Profile that defines a DFD diagram as an extension of the built-in Analysis diagram, as shown:

The Add Diagram Extension Profile Helper can assist you in defining your Diagram Profile, adding the necessary elements and giving them the appropriate attributes to define the functionality of the resulting custom diagram types.

If you have not done so already, use the Model Wizard's 'MDG Technology Builder' option to create a set of Packages for defining Profiles.

In the Project Browser, locate the Package with the <<diagram profile>> stereotype and open its child diagram.

Using the Profile Helpers


Drag the Add Diagram Extension item from the Profile Helpers toolbox page onto the diagram.  

The Add Diagram Extension Dialog displays.


In the 'Name' field, type the name for the custom diagram type.


In the 'Extension Type' field click on the drop-down arrow and select the built-in diagram type that the custom diagram type will extend.


In the 'Description' field type a brief description of what the diagram is used for.

When a user selects this diagram type in the 'New Diagram' dialog, this description will be displayed in the bottom right of the dialog.


Within the 'Properties' pane enter values for these fields:

  • Alias: Defines the diagram type displayed before the word 'Diagram' on the diagram title bar; for example: 'Block Diagram'
  • Frame ID: Defines the diagram type that will appear in the diagram frame label
  • Frame Format String: Enter a string containing substitution macros for defining the frame title, with or without additional delimiters such as ( ); macros that can be used are:
         -  #DGMALIAS#
         -  #DGMID#
         -  #DGMNAME#
         -  #DGMNAMEFULL#
         -  #DGMOWNERNAME#
         -  #DGMOWNERTYPE#
         -  #DGMSTEREO#
         -  #DGMTYPE#
  • Toolbox Profile: Enter the name of the Toolbox Profile (the name entered when saving the profile); this Toolbox will be opened automatically each time a diagram of this type is opened
  • Swimlanes: Defines swimlanes that will be displayed on the diagram; for example:
    (where Lanes can be any value, but the number of Lane<n> values must equal the value of Lanes; Orientation can be omitted, in which case the swimlanes default to vertical)


The remaining fields in the 'Properties' pane can be used to customize the diagram's default options.  Any Attributes left blank will not be applied.

When a user selects a field, a description of the property's effect is displayed at the bottom of the 'Properties' pane.


Click on the OK button. The appropriate Stereotype and Metaclass elements are added to the diagram.


Repeat steps 2 to 8 for each diagram extension to include in the diagram Profile.


Save the diagram as a Profile.

Incorporate the Profile into an MDG Technology.

  • After a diagram extension has been added you can modify its properties again by right-clicking the appropriate Stereotype element on the diagram and selecting 'Edit with Profile Helper'
