Description of Related Art
[002] Students in general have to carry various drawing equipment to schools such as, a scale, a compass, a divider, and a protractor, which sometimes become very problematic. These drawing equipment are so small that in some cases, the students loose these equipment in their bags and while finding the equipment, the students may get injured. Sharp or pointed edges of these equipment may pierce into the skin. Thus, such sharp edged equipment need to be handled carefully and properly. Moreover, traditional compass can only draw circles up to a diameter of 10 cm, which further enhances the need of a compass with a wider reach.
[003] In addition, the students carry these different equipment that increases an overall weight of their school bags causing an extra burden on the students. Moreover, such equipment may not be equally comfortable to be operated by right handed users and left handed users at the same time. Further, the conventional equipment are very harmful and clumsy when seen from a student’s point of view.
[004] There is thus a need for an efficient and an effective compass for increasing an easiness of drawing.
