I have made a start on the CAD model though. The plan is to do a full aero programme including CFD design & optimisation of an aero package, design and build my own wings etc and then finally get the whole thing set-up properly with track testing and data logging. For any of this to happen though, I'm going to need to make a reasonably decent CAD surface model of the car to start.
The model has been made using Autodesk Inventor and Catia V5 from orthographic views found on the net. It's not exactly the best way of doing it, but for my purposes it'll be good enough...
Some photos of the early CAD models:
I'll upload more photos of the CAD model once it's finished.
