A pretty great photo series shared by the instagram account @historyphotographed. Before computer aided design the use of drafting tables, paper and supplies took a lot of space. Photos span the 50s to the 80s.
Prior to the release of AutoCAD in 1982, engineering drawings were all done by hand using different grade pencils, erasers, T-squares and set squares.
Even after all the manual labor, if a change was required, the engineers and toolmakers had to start from scratch and make the sketches all over again. Nowadays, architecture designers and other drafters are mainly just clicking their mouse and keyboard and not hunched over on a giant desk wondering if any changes will be made to their final drafts.
