This seems to complex for me. Tomorrow I will make some screenshots of a
program called Aris. It is a business process modelling tool and I think a
business organisation modell is as complex as a software (UML) modell. So I
will show you how they handle it...

I thought about the current property dialogs in umbrello (version 1).

Maybe we should take a look in the area of data warehouses and data marts. I
like to mention some terms like:

- drill down and roll up
- slice and dice
- visualize (change kind of visualization like pie or bar chart)
- drill-trough
- pivot

These are technics to view a data warehouse in different views for different
tasks. I haven't seen a very good tool for visualization in this sector, but
it is possible to do these operations with Excel on spreedsheets.

The problem might be, that an UML modell has more then 3 dimensions, so it
is quite hard to show it in a 3D view.
