amapi see: www.staigerland.com for tutorials www.critical-depth.com for a free 4.15 version and my site: www.brycetech.com (www.posertech.com) for examples of what you can do with it. amapi takes a bit to wrap your mind around its use, but it rocks. And the new version 6.1 will stand right next to lightwave's modeler. Theres a big difference between 2000 bucks and 200. BT
