The first working drawing set I ever drew (in 1984) was ink on mylar. Ironically, and because the budget allowed it, I redrew the same set of working drawings on CAD (also in 1984). Great transition exercise. Then in 1985 (I suggested and) produced a set of CAD working drawings at 11 x 17 via electrostatic printer (precursor to laser printing). Duplicate sets were made via photocopy.

I still sometimes wonder if architects are really as modern as they think they are.
