Hi everyone,
This question has really been bugging me for ages so I may as well try and ask it.
Before the advent of CAD I can understand how the designers/engineers of plane could come up with 3 view sketches (front side and top) but what I don't understand is how they came up with wing rib drawings or fuselage frames, that would fit the design at any point in the wing or fuselage?

How did they decide the measurements and where frames such as this would be placed?
Thank you very much
