Finally, I looked at RibbonSoft's QCad. QCad has a few big advantages right out of the box. First, I'm already familiar with the program from having used it several years ago. Second, when Paul does need to use an affordable 2-D CAD software (when he is really slumming it), he likes this one. As he is one of my collaborators in many of the TE projects, it is advantageous to be able to easily share files. Third, it is very much like AutoCAD 2000, which means the learning curve is shorter for people with some CAD experience, and that using this software helps the rest of us to acquire real world, marketable skills. It was free when I last used the software. Now it is $37 to download, $44 to receive on CD, and $60 to order along with an "Introduction to CAD" book. As decent CAD software goes, it is affordable on all counts. I found QCad somewhat more difficult to use than TurboCAD. However, with that complexity seems to come the ability to do more. I'm willing to accept that tradeoff. The menus are more extensive and somewhat more tricky due to their multi-level structure than the menus in TurboCAD. However, I quickly got the hang of them and found them more powerful. QCad also seems to have included a form of the cursor tool tip that I liked in TurboCAD. One of the most important advantages to me is the speed at which I can move when I manage to remember the keyboard shortcuts. I also find the integration of the history and layer windows into the main window helpful. For all of these reasons, I've chosen QCad the winner of this round up.
