Two layers of sketch in the DXF files

Hi All,

Does anyone know why there are two layers of the sketch in the DXF files?
I used CorelDraw and the eCut plugin to measure the perimeter of the parts just to get an idea of the cost and I noticed that I always got double than what I was expecting. So I moved the entity and lo and behold I found there was another layer beneath it.

Cheers!

Hey!
I don’t know why this is, but I also expierenced this when uploading the files to the lasercut-software. I had to manually remove half of the lines in all the files.
