I recently found this software online. From the looks of it, it may give planners an ideal way to throw up ideas of how things may look. It seems like it'd be MUCH easier to use than any CAD program, or even easier than fudging with photoshop. I suggest watching the tutorial video. I know they make it look REALLY easy, but still, not bad. I could probably catch on pretty quick-like. Go here to see it. Seems like a pretty reasonable cost too. $500 for general business use and if you've got access to a student, its a deal at $90!
an example of what can be done. Opinions? Are there users out there?
