How do you represent Inheritance in a UML class diagramm if the base class is not part of the module. Say e.g. you have a class myScene (in your diagramm) that extends the javafx.scene.Scene, how do you show this relationship?

    I tend to draw up the classes even if they are not designed by me, then I represent them in a different colour and add a comment to communicate this. Commented Nov 6, 2016 at 21:28
  • So you just add them but with or wthout methods? I'm afraid that adding all methods would just blow up the whole thing too much. Commented Nov 6, 2016 at 21:29

    It depends on the model's purpose. If documenting a domain model for other to reference, then I would put in everything. If the purpose of the diagram is to give an abstract overview then I supposed inheriting from an empty "javafx.scene.Scene" would be ok -- again while adding a comment. Commented Nov 6, 2016 at 21:32
  • Do as @Pétur said. That's fine. You can leave away class details. Commented Nov 6, 2016 at 21:32
  • @Pétur you should make this an answer. Commented Nov 6, 2016 at 21:44
