Little things everyone should know

Years ago I ended up with a couple copies of the “Architectural Graphic Standards” 3rd and 5th editions. I don’t remember if we picked them up at a yard sale or if they were handed down from my Grandfather right now, but I’m thinking it was the latter…

Anyway, I was glancing through them last night, because I just find them really interesting, and found in the 3rd edition (printed 1946) this really interesting page of reference material. All of what it covers is readily available in many places, of course, but this was just kind of a nice presentation.

So, without further ado, here is page 301 of the Architectural Graphic Standards, 3rd edition (1946), Mathematics: Units of Measure
