Exporting DXF from Altium

[Feri4030]

Hi,

I use Altium designer to generate a dxf file for the drilling holes. The problem is the cirles appear different from a dxf viewer to another. Some shows them as circle, some as hexagonal, and yet some just as a single line segment. My technician uses Autosketch to run the laser drilling machine and sees them as single line segment.




Can anybody tell me what should I do?

Thanks

I wonder where you see a drilling whole in the picture?
