AutoCAD: Delete Duplicate Objects also known as the Overkill command

January 2, 2015

Need help cleaning up a drawing? Sometimes extra geometry can sabotage your drawing efforts by slowing you down or in the case of overlapping geometry you may snap to an incorrect point unknowingly. Now measurements may be off.

The command Delete Duplicate Objects removes duplicate or overlapping geometry. This command responds to Lines, Arcs and Polylines and will combine partially overlapping or contagious geometry.

Where to access this command:

In the Home tab, Modify drop down panel,


Or at the Command line type in OVERKILL. (Not case sensitive.)


Options once in the command:

In the video the duplicate lines and arcs are on Layer 1 “color Magenta” as to stand out a bit to be screen. The option Layer in the Ignore object property: must be selected in order for the geometry to be located. The selection of those options will vary depending on the geometry and how it was placed into the drawing.

*At the Select Objects prompt: using the default Crossing Window option helps ensure that everything that is touching or encompassed within that window will be selected.
