As a waveform the meandering stream follows the down-valley axis, a straight line fitted to the curve such that the sum of all the amplitudes measured from it is zero.
It relied on the use of parametric relationships obtained through curve-fitting procedures that had been performed on a historical repository of significant cost data.

As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous microcomputer design program worldwide, with functions such as "polylines" and "curve fitting".
