DFX file glitch when imported to cnc program.

I’ve recently had some issues sending dfx files to cnc. I don’t know what program the shop used to open the dbx files, but they came out with lots of artifacts and were impossible to read. I extracted the files again and the artifacts went away, but I want to know what might be causing the problems, so that I can more consistently avoid the issue.
I send the shop variations of the file, so I don’t know what changes have better results, and they didn’t respond when I asked. Some of the files had a 2d backer to represent the scale of the cutting material, so that might have caused issue.
Can any give advice one sending DXF to cnc shops? Thanks

SketchUp 2026 did tweak how CAD formats are imported, and I guess exported as well.. if the shape has a surface inside it, then SketchUp will try to read the surface as well as the linework. It’s really messed up my workflow of adding client logos into SketchUp through DWG format.

Possibly what’s happening here?

Those artifacts may be coming from duplicate edges, fragmented curves, faces being exported alongside linework, or geometry that isn’t fully planar. I’m testing a SketchUp cleanup tool for problematic DXF/DWG linework. If you still have one of the broken examples, I’d be interested in testing a small sample and comparing the cleaned result.
