If the scale of a drawing is unknown, slide your finger on the variable scale and match the scale of one known element, lock it and use it to measure all elements on that drawing.
With fixed and variable scales there is no limit to measuring a printed drawing of any scale, even if the scale is unknown.
If you know the scale of a drawing, place your device on the drawing, scroll to the scale of the printed drawing and watch the chosen scale slide in.
Slide the measurement slider in fixed or variable scale modes, along the scale to see the desired measurement displayed.
Let Scala Architectural and Engineering Scale change the way you measure printed drawings on the go and at your desk.
