What order should you obtain measurements from a dial caliper?
In order to get an accurate measurement you must first zero the dial caliper. This means closing the caliper, loosening the dial lock, rotating the dial to show zero, and then tightening it once again.
Step 2: Measuring the Width of a 3D Rectangular Object
To begin, we will measure a three-dimensional rectangular object. As the name implies, a three-dimensional object has three dimensions that we will need to measure - length, width and height.
Step 3: Measuring the Other Two Dimensions
Repeat this process to measure the other two dimensions (width and height) of the box.
Step 5: Measuring the Dimensions of a Cylinder
To measure a cylindrical object like a can, you would need to measure two dimensions. The first would be its diameter and the second is its height. The reason for this is a cylinder’s length and width are the same value, but its height can differ.
Step 7: Recording Your Measurements
The easiest way to record your measurements is on paper. To keep it simple, we will be practicing with the small box we measured earlier. The idea here is to do a rough sketch of the object you are trying to measure. You don't need to be an expert artist.
Step 8: Translating to 3D Software
To translate what you have just drawn on paper to the computer, open Tinkercad and create a new 3D design and give it any title you would like. I called mine "Measured Box".
Step 9: Put It Into Action
Now that you know how to use calipers to measure real world objects, you can put your new skills to work by designing a Straw Roller Coaster in 3D using Tinkercad!
Step 10: Share an "I Made It"!
Post an "I Made It" below to show us a 3D object that you measured using calipers and modeled in Tinkercad!
How to read a dial caliper?
To read a dial caliper, start by closing the flat jaws of the caliper around the object you want to measure. Then, look at the scale value that's at the inner edge of the caliper's jaws and write it down, including the unit. Next, read the value that the needle on the dial is pointing at and write that down as well.
How to read a caliper scale?
Read the scale value. The scale engraved on your caliper can be read just as you would a regular ruler. Find the value at the inner edge of your caliper's jaws. The scale should be labeled with a unit, typically cm (centimeters) or in (inches).

If your tool has one scale and a round dial instead, see the dial caliper instructions instead. If you are using a digital caliper, the measurement should be displayed on an electronic screen, ...
What is a caliper used for?
Calipers are measuring tools used to precisely determine the width of a gap or object, much more accurately than a tape measure or ruler. Besides digital models, which uses an electronic screen, a caliper can display the measurement on a pair of scales (vernier caliper) or on a scale and dial gauge (dial caliper).
How to check if dial is zero?
Check for a zero error. Close the jaws completely. If the needle on the dial doesn't point to zero, rotate the dial with your fingers , until the zero is beneath the needle . You may need to loosen a screw at the top or base of the dial face before you can do this .
