WebFlatness vs straightness. Flatness is often described as being “the 2D version of straightness”. A straightness requirement applies to a 1D (linear) surface trace or axis in 3D space, whereas a flatness requirement applies to a 2D (planar) surface in 3D space. A flatness measurement can be approximated by a series of straightness line ...
WebFlatness It is defined as minimum distance between two planes within which all the points on a surface lie.
