Arch Ruler

The three sided ruler is scaled for you. If you look close at each end you see a fraction, 1/8" on one end and 1/4" on the other. Also on the end is a set of smaller marks that is scaled for the entire inch. Example read the 1/4" scale, the long markes are for 1/4" = 1'. Read from the other side and the small marks are for 1/8" scale. The small set on each end is scaled to inches. On the 1/4" end the marks from 0 to 1/4 allow you to scale down to inches ie third mark is 3 inches past the number of feet. It is very simple once a person understands what the markings are for. If you can get a elementary drafting manual, it should be the first thing it explans in detail.
