It is a specialized ruler. It is used in making or measuring from reduced scale drawings, such as blueprints and floor plans. It is marked with a range of calibrated scales (ratios).
Tips:
Always make sure your pencil tip is extra sharp and use a drafting or fine-point pen; a wide mark could throw off your measurements, and even the smallest of increments on the paper can translate into a major difference in the structure.
Features:
✎ The architect triangular scale is made from professional grade solid aluminum, heavier than other hollow / plastic architect rulers.
✎ All measurements are Precision Laser-Etched and will never rub off or smudge.
