I recently needed a free “Visio-like tool” to do some diagrams for our latest project at work, but I don't have Visio, and I don't love using it either. Like most Microsoft tools, Visio's got way too many unnecessary bells and whistles which force you to learn the tool rather than get the task at hand done quickly. I like Graffle, but someone's "borrowing" the iMac I had on my desk so that wasn't an option either.
I did some quick searching and found this little gem, Diagram Designer 1.19 by MeeSoft, on TuCows.com (TuCows Diagram Designer product review/download).
Seek and find. This is a great freeware tool to "create flowcharts, diagrams and slide shows", and other vector stuff. It's light weight at 1.28 Mb, simple and easy to use -- and makes quick work of day-to-day grunt stuff.
The downside is it's Windows only (98 / NT / 2k / Me / XP / 2003 / Vista) no Mac or Linux. Also it saves the vectors in it's ".ddd" file format which I haven't seen before. But, you can import/export your work to other formats like: WMF, EMF, BMP, JPEG, PNG, MNG, ICO, GIF and PCX. It even has user submitted template palettes. Also, Mr. Vinther has released a previous version to Open Source.
I got great results -- and I got the job done quickly, so I figured it makes sense to share it. Let me know what you think.
Now if I could only remember where I left my cup of coffee...
