Summary

  • While various tools exist to get accurate measurements for CAD drawings, sometimes these aren’t available and you have to get creative.
  • One method is to take a photograph of your desired object, and overlay it with a metric scale, such as a vernier caliper.
  • Make sure you also photograph the scale by itself for reference, and include its measurements when photographing the two together.
  • Alternatively, put the item on a flatbed scanner and scan it with a metric ruler or similar item that includes a scale for size reference.
  • Many in the comments suggested using a mirror to make sure the lens is parallel to the object.
