I have often said to young engineers that the tools we have today were not even science fiction when I first graduated. Now a 3D CAD system can easily create complex shapes. Before the 3D programs there where products with complicated shapes. This video explains how cars were designed and the number of man hours that went into it. This old video was the closest I ever got to the advanced design studios. This was high security as indicated in the video. When I look at designs of many old products and realize the tools that did not exist then I realize how many skills are today lost. You may recognize the car towards the end of the video.
