The numerical value of radius should be measured by the ruler when the circle is drawn with the existing COMPASS. Such a method is cumbersome to measure the numerical value repeatedly when drawing various circles. It is also inconvenience to draw a circle with minute and accurate numerical value. Users may not need to measure the numerical value with a ruler all the time because the numerical value is seen in the Liquid Crystal Display of ‘Easy-to-View COMPASS' at a glance. Thus, the inconvenience of measuring numerical value with existing COMPASS is solved through Easy-To-View COMPASS.
