I have gone through various posts where people have suggested various UML tools .
I have not seen anybody mentioning NetBeans though it is also open source and available freely and should have been a natural choice since it is by SUN.Am i missing something?
As a part of design the Java code also gets generated by NetBeans. Are we supposed to send that also ?
You can look at Visual Paradigm. They have free community edition, however there will be watermarks on exported images. In order to remove them you will need to purchase the personal edition, which will cost you around 50 EUR.
