When 3d printing it would be great if when I split a body I can add a thickness to it. The reason is if I just split the body the component that I end up fits exactly the problem is that the 3d print I make grows by about .2 of a mm. If I was able to take a further .2 of a mm of the surface of the body it would fit perfectly. All this would require is the body split using a body then an option to add a further thickness to its surface when doing the split.
