Dia

Dia is a program for creating diagrams of all kinds. The current version can do UML class diagrams, Entity-Relationship modeling, network diagrams, and much more. The engine is very flexible and dynamically loads diagram-types from disk. It stores diagrams in an XML format, but can read and write a number of different formats.

            How to Set a Scale (e. g. 1:50)?
            Hi,

            Iím new to Dia.

            It looks very good. Congratulations to the developers!

            Iíd like to draw up a building plan and havenít found a way to set the scale of the canvas (e. g. 1:50).

            Can anyone shed some light on this?

            Cheers,

            Tobias

            Latex labels in dia
            I love dia, but I have to switch to some other editors such as ipe and xfig when I need good looking latex-style labels on my diagrams. Dia would be golden if it had the same option.

            DIA for Windows
            Hi All!

            Dia is an excellent tool to create diagrams. I had some trouble first to put these diagrams into my Word (Office XP) documents, but when you install Adobe's SVG viewer plugin and export your diagrams to the SVG format, you get excellent scalable diagrams!
