A curve is created in a computer-aided design system, based on a set of poin ts inputted by the user. A polyline is computed and the curvature envelope alon g said polyline is computed to determine particular points (A0, A1, A2, A3, A4, A5) on thepolyline, which are extrema of curvature. Segmenting points (M0,1, M1,2, M2,3, M3,4, M4,5) are selected between pairs of particular points. A curve passing through the particular segmenting points is computed and is fitted to thepolyline. The process provides a curve that is well fitted to the set of points and do es not require high skills from the user.
