At the beginning of the design process is always an idea from which a sketch is created. On the sketchpad or the computer screen – ideas which previously only existed in the mind of the designer now become visible.
Based on this package, which contains all geometric requirements, the sketches are transcribed in a way that ensures that the proportions, dimensions and graphics are coherent. The fine tuning is done on the clay model and the powerwall – a huge projection wall that lets the designers view their designs from various angles to analyse them. It makes it possible to envision the car in the correct size and change the geometry, colour and texture with one click. However, the virtual world is still unable to replace true-to-scale modelling to this day.
