They allow you to catch modelling errors, and more importantly, allow you to refactor models more easily. Say your 'Customer' class has been renamed 'Account' - change it in the model and all references to Customer will be updated.
Remember -a good UML model is a bit like a circuit diagram - it has rules that allow you be very precise about what you want to convey. There are approaches to modelling that mean you generate the application rather than code it directly or code very little of it.
What are you trying to achieve with your UML diagrams? This might help people answer your question more precisely. Also - if you have a requirement to use UML 2. Rational was the best UML tool in the world but since its eclipse integration and the use of the GMF framework it is now so unstable, so slow, no direct control of the model etc The Unified Modeling Language UML is the industry-standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems.
It simplifies the complex process of software design, creating a 'blueprint' for construction of software systems. Rational Rose could also do source-based reverse engineering; the combination of this capability with source generation from diagrams was dubbed roundtrip engineering. The Rational Rose family allows integration with legacy integrated development environments or languages.
