System and a method for drawing arcs and circle
摘要:
The embodiments herein disclose a compass for drawing arcs and circles without the need for accessing the center. The compass comprises a chassis fixed with a first guide wheel and a second guide wheel at two opposite ends. A protractor is fixed to the first guide wheel for setting an angle for the first guide wheel. An offset wheel is installed under the offset axis frame arranged perpendicular to the chassis next to the second guide wheel. A tool holder is mounted on the offset axis frame using a clip. A laser pointer is mounted on the offset axis frame for identifying a desired part of the arcs and circles. A balance wheel is attached to the balance base arranged perpendicular to the chassis for maintaining a stability of the compass. A marker is inserted in a tool holder for marking the arcs and circles.
