3D design in 1975

In 1975, people were doing 3D design on machines like this one, without a mouse, without color monitors... Interestingly, the male protagonist in the picture is named Jef Raskin. He was the inventor of Apple's Macintosh and Canon's Canon Cat, and it was he who created the mouse that could click and drag. He was also a renowned expert in the aerodynamics of micro air vehicles (which is why you see his 3D design is an airplane).
