Descrição
The Ultimate Drawing tool!
but watch out! This protractor/ruler uses a 420 Degree system. Ideal for drawing exact 7 corners.
where you normally devide 360 by the amount of corners of your rectangular polygon. this one should be 420 devided by the number of corners....
So for this protractor. your normal 60 degree angle. Is 70 degree ;) Cause 60 degree would result in a 7 corner.....
- 90 degree angle = 105 degree
- 180 degree angle = 210 degree
Enjoy!
