"WebSpline-fit polylines are very different from the curves produced by the Fit option. Fit constructs pairs of arcs that pass through every control point. Both of these curves are different from true B-splines produced with the SPLINE command. If the original polyline included arc segments, they are straightened when the spline's frame is formed.
