How to convert polylines to circles in Altium Designer or solidworks

[Feri4030]

Hi,

To fabricate holes in PCB the fabrication facility needs to have full circles at the position of vias NOT polylines (because the drilling machine will try to cut the polyline and will not use a drill to just make a hole). But I have my file converted to dxf from HFSS where all of the circles are polylines.

Is there anyway to convert circular polylines to vias or full circles in altium designer or solidworks?

Thanks

For drilling the PCB, the fabrication facility only needs the drill file, not the DWG or DXF.

The problem is not that in the original HFSS design all of the vias are segmented polylines so in any kind of drill file they would appear as a circular polyline. If you give this to a milling or laser machine it will not treat them as a hole, instead it will try to cut the edges as by following the polylines.

I found a software that can convert the circular polylines to circles but it's not free. I'm looking to find a free dxf editor with this feature.
