seems to be working for me in my efforts to design a major remodel project. It is taking me considerable time to unlock the power and streamline my work. But it's pretty satisfying as work progresses. It makes it very easy to try different ideas. Save your work often though, or you'll find yourself wishing you could go back to some mid-point between two saved versions of your work. File management strategy might be handy, I'm beginning to think. The available tutorials are fairly helpful in the quest to learn to think as the program does.
Sharing files with other programs requires the pay version (Pro 6) for $495, though you can easily share with somebody who also has SketchUp. Whether I end up needing Pro6 remains to be seen. Printed output is easy and should fill my permitting needs. Right now, this tool is helping me get it done.
It's fun just for doodling too. Another cool tool. If you don't have CAD software, this is much better than what you have. If you do have CAD software, I'd be interested in comparisons.
-Dean squirming in my chair when it doesn't do what I expect. I can see how this work all day every day would wear on the synapses.
