I am new here, I am currently undetaking a 3rd year dissertation for the construction of a web site. I am drawing my use case diagrams. I have a few questions:

Firstly, can use cases be drawn in levels. I.e. a high level use case, then lower levels.

Secondly, if i create lots of lower level use case diagrams i.e. outlining specific tasks, can these be placed in packages to show the high level use case?

Thanks very much]]> http://forums.visual-paradigm.com/posts/2685#20280.html http://forums.visual-paradigm.com/posts/2685#20280.html
it depends on, what you mean with "low level" and "high level"?
If you mean details = low level and abstract = high level, than you can define relation between your use cases:

- include
- extend
- inheritance

like classes, but just don't go so much into details for presenting use cases :?
