Usually, you draw a circle with a compass, a specific angle with a protractor, a straight line with a ruler or triangle ruler. Less ruler combines functions of compass, protractor and straightedge. With a Less Ruler only, you can not only draw straight line, but also circle with any radius, angle with any degree. It is more convenient and easier for your drawing work and most importantly reducing the cost requirement for rulers of each person.
