I have read posts back as far as 2008 indicating that you can show or hide individual attributes and operations in a class diagram. Unfortunately, in examining the property dialogs of both the diagrams and classes, I am not seeing those check boxes or options that would perform a show or hide for the individual attributes or operations. After several layers of inheritance, implementation classes can have an enormous number of attributes and operations, making the creation of a concise diagram to communicate a concept difficult. Could you please point me to a help topic or tutorial or white paper on how to do this? Thank you very much!
