Working with the UML Navigator

The UML Navigator can be opened through:

Window > Show View > Other... > Together Modeling > UML Navigator

It displays a logical view of elements that comprise the project's model as shown:

The UML Navigator displays the root-level packages that comprise your project, enabling you to logically navigate the contents to see subpackages, diagrams, and diagram elements.

NB: The UML Navigator's view is not strictly hierarchical in the same sense as a file system explorer because the project's root-level packages can physically reside anywhere within the project, and not necessarily at the same level. For example, when setting up the project you may have specified more than one source directory within the project, src1 and src2 (this approach is not recommended, it is only used as an example). If in src1 you have package1, and in src2 you have package2, you will only see those two packages in the UML Navigator. When you create a new class in package2 it will create it in scr2/package2. If you create classes in the default diagram, they are created in the first source directory (these are sorted alphabetically).
