i dont know why any of the figure are screwed up first, try exporting one figure at a time, and click universe and ground off. make sure you are exporting them as wavefront objects (best for this). so when you get to the hiearchal window, click the universe checkbox off, and then figure1 and all its parts, and export, and then repeat the process ofr all firgures... i dont know if doing them seperatly will help any, but sometimes that type of thing will help, i do it that way and have had no trouble...good luck! :)
