I am trying to specify that a particular attribute is a static attribute. I know that according to UML specification, static attributes/operations should be underlined in the class diagram, but I cannot figure out how to do this. I cannot underline an attribute using the “Format”–> “Font” option, and I cannot do this from the “Class Specification” dialogue box either.
Well, you normally don’t. It’s not something specifically supported by the UML specification. A common practice by some users is to use a note which indicates that the class is static. But normally only a class members are denoted as being static or instances.
