Calibrating the Ruler

Introduction

When a measurement is not available, the ruler displays the value expressed as mm (millimeter), in (inches), or cm (centimeters). Use an object of known length as a reference to calibrate the ruler.

Manual calibration does not apply to volume annotations in 3D sphere.
