Arc Offset

The Arc Offset tool will replace any line, polyline, spline, Bezier curve, or arc, with an arc with a fixed offset from the chord line. The offset is the distance from the midpoint of the arc to the line between the start and end points. The chord length will be the start and end points of the selected element.

Select the Arc Offset tool on the ribbon or press Shift + U. Any elements that are not allowed for this tool will be dimmed.

Set the offset value. Mouse over an element to see a preview. Click the element to accept the replacement. You can also marque select multiple elements. Left click, drag the marque, and release. Elements will be previewed as you drag. When you release the new elements will be created.
