Basic, Fortran, Cobol(sp?), it was all Geek to me in my Engineering Discipline. I used to have to carry a T-square and other assorted drawing stuff for my “engineering graphics class”. Thinking about and drawing those 3D graphics really made my head hurt.
I drew with ink on mylar until CAD software and plotters dropped to where I could afford them. I did have a rather marvelous track-drafting machine to speed things along. Not sure they make those any more.
