摘要

The assembly has two rulers in which one ruler is in the form of inner and outer rectangles and the other ruler is in the form of two parallel lines. Two rounds are preset at ends of the latter ruler, where the rounds are positioned in a manner to trace any rounds of letters e.g. capital letters, and numbers e.g. Roman numbers. The rulers are rigid and calibrated, where thickness of the rulers is higher than one millimeter. The rulers have a bevel on inner and outer edges.
