Remove Duplicates Lisp Routine

Remove Duplicates Lisp Routine

Remove Duplicates Lisp Routine

(OP)
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
  

RE: Remove Duplicates Lisp Routine

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,
