Bushi's tute will get you going. I bugged him about DD's missing joint parameters (XY &/or Z Rot). He advised me to just remake the phi, which was exactly the problem I was having. He wrote that tute many moons, ago, in early (late actually) the Poser 3 Millenium. Things haven't changed in this respect. There's 9.5 pages dedicated to editing Joint Parameters in the Poser4 manual pages 278 to 287. Coop said just read that, play for a day, & you'll get the hang of it. Worked for me...
