What This Means for Your Design

Imagine you want to make a perfect copy of a violin's wooden top. Instead of just looking at its curves, this method uses special lines (contour lines) to create a super-accurate math formula for that exact shape. This formula can then be fed directly into a computer-controlled cutting machine to make an identical copy.
