How to use

Place the ruler on your drawing or model surface aligning the appropriate scale with the measured length. Read the value directly from the scale corresponding to the desired reduction ratio. Use the high-contrast markings to trace lines or check dimensions; work on a flat surface for best accuracy. Clean with a soft cloth to remove dust and avoid solvents that could damage the plastic.

Recommendations

For accurate results, select the scale matching your drawing’s reduction and ensure the ruler is firmly positioned before marking. Store the ruler flat to prevent warping and avoid exposure to high temperatures.
