You can turn a spline-fit curve back into its frame polyline by using the PEDIT Decurve option. When a spline-fit curve is fit to a polyline, the spline-fit curve's frame is stored so that it can be recalled by a subsequent decurving. Tangent specifications on control point vertices have no effect on spline-fitting. Once spline-fit, the frame, if displayed, is shown with zero width and CONTINUOUS linetype. All intermediate width information is ignored. If the frame has width, the resulting spline tapers smoothly from the width of the first vertex to the width of the last vertex. If the original polyline included arc segments, they are straightened when the spline's frame is formed. Both of these curves are different from true B-splines produced with the SPLINE command. Fit constructs pairs of arcs that pass through every control point.
