Fit Polylines

This feature allows you to use a variety of best fit methods to smooth an existing polyline.

Prompts

First you must choose the method to use in fitting the selected polylines at the following prompt:
Type of fit to apply: [Decurve/Fit/Quadratic_spline/cUbic_spline/Cg_spline]<C>:
Next, select the polylines you wish to fit then press the <Enter> key or right mouse button to apply the fit to the selected polylines.
Decurve: This will decurve a previously smoothed polyline.

Fit: uses CAD fit – a series of interconnected circular arcs.

Quadratic spline: Uses a quadratic spline curve fitting algorithm.

Cubic spline: Uses a cubic spline curve fitting algorithm.

C&G Spline: Creates a smooth curve that passes through all vertices.
