Let me thank everyone for the fast responses.
which dxf looks good on your machine? Did you export both in the same FreeCAD session without doing anything else? Yor files don't contain the unfolds. How did you unfold?
Yes, I did the exported all part in one session without doing anything else. For the unfold I touched the part, select the unfold item (not the unfold sketch) on the tree view and executed. After I unfold I do not save the part, I only unfold for the export. I find the unfold and the part in the same drawing a bit confusing.
OP, welcome to the forum. Note: our guidelines request that users refrain from posting their FC info in their signatures. We ask this to specifically prevent misunderstandings since versions can change but past posts are static. Thank you.
Sorry about that is been corrected.
If you are using the "legacy exporter" (first red box), try unsetting the "Treat ellipses and splines as polylines" (second red box).
I though that only applies for the import, others have confirmed that. Thanks.
I will try to be more specific. Like I mentioned before I am using the same unfold and export procedure for all parts but getting different results (that is why I suspected I did something wrong during the drawing process). On the drawings that I included Tapa Frente560 is OK I get circles when open on the plasma software, on the other hand when i opened Tapa Motor560 I get hexagons. To be honest I can edit the DXF on the CNC software StarCam, I just want to understand what I am doing wrong that causes inconstancy.
As you can see here I get circles.
Here you can see the hexagons.
