Life before the invention of AutoCAD, 1950-1980 - Rare Historical Photos

Before the advent of AutoCAD and other drafting software, engineering drawings were made on sheets of large paper using drawing boards.

Exactly like that. I started my drafting career in the late 60's and I still remember all that very well (white shirts & ties were a requirement). Still have some of my old manual drawings & tools. Started in the CAD world in the late 70's with what were at that time, still 2D drafting systems. Shortly after we had a "CADAM" 2-1/2 D system - once you created 2 views the system would let you project the 3rd view. Early 80's we finally got an actual 3d system. So, seen it all & loved every minute of it!
