what software you use to create UML's?
ajg1977: Visual Paradigm -* It's cross platform (I use it at work on PC and home on a Mac).* The pricing is very fair, particularly the single-user edition ($70).* The community and viewer editions are free.* It has nice support for automatically aligning/formatting/reorganizing diagrams.On the downside the toolbar isn't that great, many common operations are in the main or context menus. Also the diagram explorer doesn't support subfolders for grouping things together.http://www.visual-paradigm.com
