Calibrate Your Drawing

The first time you add measurements to a drawing, you will first have to calibrate the drawing. 

  1. Tap the Calibrate tool.
  2. Find a place on the drawing where you know the measurement (i.e. the length of a wall). Tap and drag the calibration to the end of the length.
  3. Enter the length in feet and inches (imperial) or meters (metric).
  4. Tap Save.
    Note: If you ever delete this calibration, all of your measurement markups will still be in place. However, they will be re-calculated when you add in a new calibration.
