When I first heard about the 3D body scanning machines, I was excited. I thought that this was the answer to getting exact measurements for block making. I read about it online, and it said that the machines were free to use, and it would print out details of your measurements.
When I went and tried it out, all I got was the basic measurements: Bust, Waist, and Hips. (Note: this is in Australia, is it different in the USA or other countries?).
I also got other information which I wasn't really after such as weight, percentage of body fat, waist/hip ratio, etc. I also got a print out of a 3D representation of my body. What I didn't get was what I wanted: my detailed measurements such as Centre Front Length, Centre Back Length, Full-Length Front, Shoulder Slope.... etc.
