Curve issues when exporting as dxf

I think I saw something on this earlier, but when I try and export 3dm to dxf, it is exploding circles into hundreds of lines, instead as a closed curve; is there a way to check how the circles (holes in a surface for cnc fab) are being created? I am using the circle from center/radius command. Creates big issues for laser cutting

What does your export scheme look like? In the Export dialog, click Options.
