Throw Back Thursday – Old Drafting Standards Wisdom

I found these in my old CAD and Drafting standards boxes and had a good chuckle and thought I would share on this Throwback Thursday. The following were from a Drafting Standards Manual from Ralph M. Parsons Company in 1975 and were titled the Basic Dozen..Although the illustrations and terminology may be out of date the wisdom is still true to this day.

Enjoy these Basic Dozen excerpts from 1975.
