Hi - and welcome to the ranch.
What do you use UML tools for:
------------------------------
UML (Unified modelling language) is an effort to have a unified "language" to graphicaly model, for instance, class diagrams or use cases. Take a look at
http://en.wikipedia.org/wiki/Unified_Modeling_Language for more information
Which UML Tools are used today:
-------------------------------
I dont know which UML tools are mostly used at the moment. My favorit tools has always been the pen & a paper. Im not that concerned with obeying a standard - what matters is that the vision or idea can be communicated.
When I was studying it was possible to get a free edition of: Poseidon, ArgoUML and Visio. They are all "okay", but each of them has certian drawbacks.
Atm. im using either Visio or Rational Architect.
You can find a list of tools here:
