  • I sincerly think this program the perfect software I ever used! => have a look at this webiste for Free keys : www.scripts4geeks.com

  • Works great. I use it for drawing process flow diagrams and it has almost everything I want (other icons I have created...)

  • I have used Dia for my own side projects and, as a professor of computer science, I have recommended this tool to my students for their UML diagrams. I find Dia to be easier to use than others that I have tried, like Microsoft Visio. I like it's many features, including export to various image formats that enables me to create clean diagrams for use in things such as assignments and exams. Students like the fact that it is cross-platform, which enables them to use their personal computers with Windows, OSX, and Linux and share the .dia files. Some diagramming tools use templates that create a whole diagram for you. However, they tend to be hard to modify. With Dia, UML diagrams are build up by component. This provides more flexibility but can have its own issues and takes a bit more time. One issue that my students and I typically face is too few connection points on a class object. This makes it difficult to use autoroute and not have lines overlap.

  • excellent! thanks
