With the help of complex CAD techniques the chosen designs turn into three-dimensional models on the computer. Each product is engineered in a very accurate way with regard to the technical details and dimensions whereby technical problems can be solved easily.
Then renderings (computer graphics) of the 3D models are created which already present the products in a photorealistic way. Series of pictures and animations illustrate different techniques.
Subsequently, rapid prototyping models are made within a few hours. These models are made of robust synthetic material and approximately correspond to the final products. Technical modes of operation can already be simulated on these prototyping models.
