Remove Duplicates Lisp Routine 1

[Stoker]

I am importing dxf files from another application. The imported files contain two copies of all the entities. In my case the drawings will contain only lines and arcs - no blocks, text or complex entities. I am looking for a LISP routine which will remove all duplicates from the drawing.

TIA

If you have Express Tools (an add-on from Autodesk for about $150), the command is OVERKILL. Many lisps out there to do this, one was deldup.lsp I found remdup or something at following site:

Hope this helps,
