The Edit Arc/circle function is used to modify a partial or complete circle or ellipse.
To edit an arc, you must first position the cursor somewhere within the interior of the desired element and then press <left mouse> or <Enter>.
In the event of overlapping targets, items on the current layer are given preference over those on other layers, and items with smaller radii are given preference over those with larger radii.
A dialog box will appear listing the selected arc parameters. No global editing options are available.
Arcs contained within components are accessible only from the proper layer.
