Aldsron, Assuming a Poser figure to be 6' tall(as is the stock P4NM figure Dork), you could then scale a scene relative to 40.96 Bryce units being equal to 6 feet. As you say it's arbitrary, but you could do it. Inrerestingly enough, geep says that a cubit is from 17 to 21 inches. (I think that that is correct, but I can't think of where I would know that from.) Thanks for the info, - TJ
