2D DXF Export issue

Hi All

Im hoping someone can help me on exporting some 2D data for cnc. I have this weird 2d shape and I need to export it as a DXF however the export result presents extended loops.

Would be really usefully if some is able to share their 2D CNC export settings.

Many thanks!

Export scheme: Standard creates good DXFs.
Looks like the importing app has difficulties?

You can _Convert the splines to arcs and lines only.
Then export this result.

The curve is open (endpoints do not match), try closing it to see if that fixes it.

@Charles - I did look at the covert option but it changes other curves too much in when tweaking the tolerence.

@cdordoni you are right for some reason its opened during that export. I have other closed curves that are doing weird stuff.

I would be grateful if anyone has a good 2d export setting.

I don’t see anything wrong with the Default scheme…
Can you tell which software imports the DXF?

The problem related to 1000s of closed curves within a pattern. It was strange I would export and discover loops in the new file. Reedit the the data and export with some more random loops. I have never come across that before. The workaround was to explode the curves and the export. So it appears the issue relates to joining and not the exporting

Thanks for helping
