Step 1

Select a SOLID shape, preferably a shape similar in size as the one you encountered a discrepancy in your measurements. For example, if you scanned a leg, the best would be to scan a shape that looks like a leg. In the picture, that is what we used.

A solid shape is essential because studies demonstrate that if you ask 10 people to measure a real body part, like a leg, you will get 10 different measurements, depending on how strongly you pull on the measuring tape. Also, skin is malleable, the leg can be larger or thinner, according to the angle of the leg, the temperature, humidity, and other factors.

Step 2

Place at least 4 markers around the dummy part, in the most horizontal manner, on the same horizontal plane. For the markers, you can find some at any office supply store (see picture below). Use contrasting colors.

These markers will guide you on where to lay your measuring tape, to reduce the risk of error when you put your measuring tape around. The reason is because we know a slight variation on the angle of the tape relative to the horizon may induce another error in your measurements. Do this for 3 horizontal circumferences so we can get at least 3 sets of measurements.

Step 3

Scan your dummy part with color. Use the smallest scanning box possible that will contain your shape or use the automatic box placement strategy in 3DSizeMe settings. Make sure you see all the markers on your scan, identify them on the iPad with the pinpoint tool and transfer the scan from the iPad to your computer.

Open the iMed scan with MSoft and zoom in to make the shape the biggest possible on your screen. Then, use the custom measurements button and select 'circumference'. With your mouse, place the circumference exactly on the center of the markers. Note the exact size reported by MSoft.

Step 4

When you are done with the digital measurements in MSoft, take the measuring tape and take the same measurements on the dummy part, making sure you put your tape on the center of the markers, all around. 

Step 5

Please send us your digital and manual measurements (you can use the table attached below), and a picture of your dummy part, with the measuring tape around, if possible.
