Bezier Fit
The Bezier Fit tool is a very effective smoothing tool that can save a lot of time when creating or editing patterns and when preparing to cut. The resulting Bezier curve will have as many segments as needed to fit the original line, polyline, or spline, within the requested tolerance.
Select the Bezier Fit tool on the ribbon or press Shift + I.
Set the desired tolerance using the slider or the edit field. Mouse over any candidate to see a preview of the replacement. Click the element to accept the replacement.
