Reduce Polyline Vertices

This command removes points from a polyline, without significantly changing the polyline. The offset cutoff is the maximum amount that the polyline can move horizontally and vertically when removing a point. For example, in a polyline with three points in a straight line, the middle point can be removed without changing the polyline. The below image shows an example. If the offset cutoff were set to 0.10, the upper-left wedge would be removed, but the lower-right wedge would not.
