After having a rumage through some of my 3D magazines i rembered that one of them had a really good tutorial for modelling a car starting with cv curves. As I havent tried modelling like this before I thought that I would give it a go. So far it seems a really effective way of working, I have most of the shell made now and then it will just need to be filled in. I have taken a snapshot for you to see where I am at so far:
As it stands it is just an outine of the major parts of the vehicle but this will now allow me to extrude between the curves and work into it to create the rest of the car and then once done it will just need to be copied and reflected across one of the axis. So far so good.
