Lines of Superficies The marks are not equally spaced.

Creating the Divisions (Superficies) Point A: center of Circle AB perpendicular to AC Marks of AD are 1/10 of AD AE= ½ AC Marks of AE are 1/10 of AE Create circles with center AE 1 and radius AD 1 Find intersection this circle and line AB and call it B 1 This will be the first mark on the side of each ruler. Continue with each point AD i, AE i and AB i.
