    Thank you for your answers, unfortunately your link doesn't show the example I am looking for

    I am looking for an example like this:

    Actor Student -> Use Case Enroll in University -> INCLUDE -> Enroll in Seminar
    International Student -> Use Case Perform Security Check -> EXTEND -> Enroll in Seminar

    So Use Case Enroll in Seminar is used at the same time with INCLUDE and EXTEND

    I can imagine cases, but have looking for it with google, with no luck.

    Here is something else that I've found

    Scroll right down to the bottom image. One use case 'Play Loaded CD' is both included/uses and extended.

    Might be of interest but I haven't had time to read the article so I'm not sure.
