The design process for a motor vehicle component part by making drawings of cross sections of the part at spaced intervals along the surface. Cardboard templates are cut to the cross sectional shape of the inside of the part, and mounted on a rigid base at the same spaced intervals as the spaced intervals of the cross sections of the drawings to define a skeletal frame. A sheet material such as cardboard is adhesively bonded to the skeletal frame, to define a rough model of the part. This rough model is then layered with glass fiber and bonding resin and finished to the desired outside finished surface dimension shown on the drawing. This provides a finished model of the part, or the glass fibers and bonding resin build up may be removed from the cardboard to be a prototype part. Furthermore, the model may be used to make a mold from which a number of prototype parts may be made.
