Customizing the default settings for messages

You can customize the default settings for sequence diagrams and communication diagrams to show message signatures, operation signatures instead of message signatures, or message signature parameter names to visually represent communication in interactions.
To customize the default settings for messages:
  1. Click Window > Preferences.
  2. In the Preferences window, expand Modeling, expand Diagrams, and click Sequence and Communication Diagrams.
  3. On the Sequence and Communication Diagrams page, 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.
