Hi to all, new here and not expert in Autocad.As for CAD Tip #3525 i try to remove double line of same layer on plane figure stacked lines - overlaid.In Autocad 2022 (not Map) i used a various set options in dialog box of "overkill" command (brush icon) whitout success.About CAD Tip #14477, i need to remove only double line: it's necessary run it?Any suggestion ? (Please note,  in the complex drawings for photoengraving processing may occurhundred of this situations and they are not allowed)

Tip #14477 won't help in this case. The Overkill command resolves only duplicate (or almost duplicate) lines. But your drawing may contain overlaid lines in diferent elevations, or segmented lines over a single-segment line or other special cases.

Thanks for a reply Vladimir.Gently, do you know if there are other ways?Regards.

There are pobably other ways but I will need to see the drawing or at least a part of it to explore the specific case of overlaps.
