02. TactiPad – Drawing tools – The Ruler

The ruler

The ruler’s width is 4 centimeters, and it reaches 43 centimeters long. With this length,  it stretches diagonally all the way over the entire drawing surface. At one end of the ruler, a 2 centimeter wide round hole is made. In the rest of the ruler there’s a 2 centimeter wide groove. The hole and groove function to fixate the ruler in any direction across the drawing surface, by screwing the knobs.

The groove gets interrupted twice; for solidity and as recognizable points two little ‘bridges’ have been made which cross the groove each at a distance of 10 centimeters.

Little slots indicate the 5 centimeter distance in between. The ruler has a measure designation on both sides, for a length of 35 centimeters. When horizontally or vertically placed, with the hole over a knob, the zero of the ruler is on the edge of the sheet. For drawing a line at a precise position, take in account that the rulers edge is 1 centimeter wide.
