With very similar parallels to your comments about the math notes (above), it was always quite obvious which of our technicians had worked in the “old days” by drafting by hand, and which technicians had only started their work after the CAD revolution. The old school draftsmen who made the transition to CAD were the ones whose drawings made sense, and communicated varying levels of importance via line weight, line type, and so on. Their drawings were well composed and worth saving. On the other hand, far too many folks who had only drawn using the computer drew plans where every single line had the same weight, details and callouts were squeezed into tiny places that should have never had notes squeezed into them.
