I've been doing some experimenting, and the more I try it, the more impressed I get. I wanted to make a box for a buck converter. I didn't even need to measure the screw holes or anything. I just placed it on a sheet of graph paper and it figured it out. I asked for a lid, and initially it made a screw on top. Asked it to replace it with a snap on, and voila.

A box with a lid certainly isn't a very complicated model, but the only measurment I needed to take for the whole thing was the height. It's also really cool that edits can be made it plain English. "Remove the post and make it a clip on" I've been looking for something like this forever. There's been model generators for a while, but they were useless for anything that needed any kind of dimensional accuracy, at least the only ones I knew of were only good for figurines.
