Our favourite example of poor decision making regarding materials was for a multi-million Euro project to recreate a famous prewar racing car and the choice of bronze was defined by the question “what is the cheapest”? This actually happened.
At CAD Car as well as cost matters of environment of use, sustainability, aesthetics, strength and much, much more go into ever decision regarding materials and finish for parts and tooling.
