Black Ruler
New Solution for Angle Measurement and Offset Line Drawing
Wu yao is the main designer of the project. Working with his team, he has been working on product design for measuring tools. This is a set of tools made up of a protractor and an offset. A protractor, used to measure an angle or to close a space through a normal diagonal, is a better way to measure a three-dimensional angle. The offset ruler can draw the offset line quickly thanks to the circular rolling principle.
