There are a number of free or very cheap modelling programs out there that can do what you want. Please follow the link to a site which gives the most comprehensive list I've ever come across. This question has been asked before, and the general conclusion is that nobody can agree on which is the best program to use or learn, its personal. There's a very clear tutorial on the process over at SAMS3D Good luck. Happy modelling, and let us all know if you come up with anything regards peejay
