Actually the easiest would be not to add a floor or ground to the scene until you're all z'd. But that kind of defeats the purpose of being able to run the script again and again if you rotate. :) Have you tried the script? You don't have to add any cubes yourself...it's all automated! I just want to easily find the cube the floor, for example, is attached to. I've been loading up old scenes and running the script. No preparation necessary!! It's great!
