CAD-drawing of NXT robot

Take a good look at this image; it's not a real photo. It appears to be a CAD-drawing of one of the NXT robots. (See the earlier post, "Some new NXT robot variations" to see an actual photo of this robot.)

I have a few questions:

(1) Was CAD software used to create this image?
(2) If CAD software wasn't used, was a photo simply manipulated to create it?
(2) If it is a CAD design, will the software be made available to NXT users?
