Nifty and slick design, but I don't know if it has much use.
CAD users input commands from the keyboard or use a precise input device like an oversized version of a wacom tablet. Waving in mid-air only seems appropriate when you're working in 3D and want to spin around the view in your viewport. But since they have hold of the keyboard or mouse anyway, they might just do it that way rather than getting their arms tired.
Writing in the air? Good luck with that when even writing on a whiteboard takes practice, and there you got at least some support of the marker pushing against the board. You also have no resting surface.
The only practical use I see is in games, if they can overcome the chicken-or-egg situation, as a (cheaper?) alternative than a Kinect to operate public information kiosks, or just when you want one-handed browsing through your porn collection.
