The smoothing replaces original angled path with a smooth pathg. While angled path had only few points (angles), smooth path has tenths or hundreds of points. Thus, to change the smoothing of the path, undo smoothing, reposition points on the angled path (as explained in Edit points on rules) and then reapply smoothing.

If you've already closed the page, undo is not available, and the only way to adjust the smooth path is to delete it, to draw a similar angled path, and then to smooth it as explained above.

To change smoothing on a smooth path (when an undo is not available or inappropriate)

To reduce number of points on a smooth path

Select a smooth rule, click the smoothing icon , and then select smaller radius and number of steps, and then select Yes for simplify.
