WebRoundness is a comparison of a measured data set to a best-fit circle, i.e. a two-dimensional shape. A roundness measurement is a property of a circular profile in a given 2D plane. So you can for instance talk about the roundness of, say, a 3D cylinder, but this is not the same as cylindricity, which is measured simultaneously at every point ...
