get a modeling porgram such as TrueSpace, there are many many programs out there to model in, and many more personal preferinces as to which is the best program to work in. my advice is to look for the demose of some modelers and dl to try them out. get the one that makes the most sence to you. Rosaty has a number of forums dedicated to 3d modeling programs. They would be a good place to start. hope this helps Laters vel
