Mona- Ideally, you could use the method Cage mentioned that is in the Poser manual, but I wonder if anyone has actually done that for something as complicated as a mermaid- Poser doesn't actually do what it supposed to do, and some of the joints come out backward. What most people do is what Cage mentioned, create the geometry for an new object file, then hack one of the existing Poser .CR2 files to use the new object, that way all the joints are all ready set up, you then modify what you need to adapt it to the new geometry.
