Double line in DXF file

I am exporting a file as a DXF file but I see double circles when I zoom in. How can I resolve it?

You are exporting both edges and faces to 3D so the circle is exported as a circle and the polygonal shape is the resulting polyface.

I am sorry t say I didn’t get it. How can I export only Edge?

It is in the Export Options:


Thank you so much sir. You are the best
