What a good memories those days were! - I did from 1972-1981 all about hand drafting production, then pc came and spent 50-50% drafting parts in the cad program and the other finished by hand until 1986 if I remember right... since 1986 it is all about using the CAD stuff... But I still do some of my work by hand drafting... the rules of drafting today as has been said are more of personal style, dedication and love of what you do... In the early days when I started I did a lot of Civil work, and a letter size drawing including a single lot layout, that was used for the sales persons, was paid at 20 US dollars it was a lot of money back in 1976 (at least for me)... a sheet including a residential subdivision project with the lots and all the dimensions was paid at 800-1200 us dollars, if you were doing sections for road designs or streets, the kilometer was paid at 60 dollars, I used to do 10-12 kilometers a week, all the work in a millimeter paper, using the 60-80-120 Leroy lettering rules and the graphos...
Here are some of the tools I used on those days:
