Menu : CURVE

Command: Change:Interpolate

Shortcut : None

This command creates a smooth B-spline or Bézier curve that goes through (interpolates) all the points of the target polygon. The program asks what type the resulting curve should be.

The interpolated curve will be stored after the target polyline. You may thus compare the resulting curve to the original polygon before deleting the polygon.

With interpolation to a B-spline curve, if there are significant differences in the distances between the points to be interpolated, the resulting curve may not be as smooth as desired. With Bézier curves, the spacing of the points is not so important.

Finally, it is not advisable to interpolate a very large number of points. It is recommended that you use the command CurveÞChange:Approximate instead.
