Well, I would most likely use Rhino for that, since exact placement of objects is quite easy, but also it could be done in Poser, and then the whole mess could be exported as .OBJ. For that matter, with some intelligent parenting of the different objects, and some work in the joint editor, you could even make it pseudo-poseable in Poser. And taking that one step further, one could even turn it into a "character" .cr2 with PHI Builder and Poser....bloodsong could probably do it in about an hour, but I would need at least a week, LOL...
