Customizing the message signature settings for UML sequence diagrams

You can customize the global settings for UML sequence diagrams to show message signatures, operation signatures, or message signature parameter names to visually represent the communication in interactions.

To customize the message signature settings for UML sequence diagrams:
  1. Click Window > Preferences.
  2. In the Preferences window, expand Modeling and click Sequence and Communication Diagrams.
  3. In the Sequence and Communication Diagrams window, complete the following steps:
    • To show operation signatures globally, select Show Operation signatures instead of Message signatures.
    • To show message or operation signatures globally, select Always show signatures (overrides individual Message settings).
    • To show parameter names in message signatures in the <parameter name> = <argument value> format instead of values only, select Use "<parameter name> = <value>" notation in Message signatures.
  4. Click OK.
