I thought you guys might like this. I've created probably 5 or 6 different 914 3D models in my time, each with increased accuracy, but all had an element of "eye-balling" it.
Through a project I'm on I was able to get 3D scan data from a car and have been modeling up the most accurate model I've done to date. It's a long road ahead, but the body will be right on once it's finished. For the uninitiated, a 3D scan creates a point cloud which can pretty easily be converted to a polygon model (millions of little flat polygons) To create a true CAD (nurbs) model you essentially model over the poly model, picking up key points as you move along to ensure the new geometry is as close as possible to the scanned geometry. Think of it like tracing over a photo with tracing paper. The new CAD geometry is what they call class-A surfaces, it takes quite a bit of work to get the new surfaces to match the scan but also be smooth (scan data has a lot of noise) Oak green-ish color is the new geometry, matte blue is the scan.
