tomigo Edited 2023年01月23日Love the Dia tool. Have been using it since 2002 for a variety of diagramming needs. Easy to use and very flexible. And today I learned something new. How to copy objects from one Dia diagram to another!! You guys rock!

mmk47340 Edited 2022年07月31日I have used this free app to create many presentations. It is excellent. Best value for FREE. The only gripe I have is the level of difficulty in saving it in other formats, such as Power Point or PNG.

techwriter-va Posted 2022年03月04日I would've given this software 5 stars if there was a "print review" function. Large flowchart plus inability to change display units to inches (so I didn't know the actual size to choose the appropriate paper) resulted in a few tries in paper sizes and scaling to get it right on the page - especially converting to pdf. Having said that, this little program was easy to use; had all of the functionality I needed to produce a flowchart and has a lot of different options for output formats. Just a little clunky in being able to size the output. I think this is pretty great software when your company doesn't want to pay for Visio. (There should be an "N/A" next to "Support" - it was so simple I didn't need Support so I gave it a "4").
