Exporting DWG or DXF and importing it back leads to artifacts
On importing .dwg or .dxf files into illustrator (even for files that have been exported from illustrator in those formats), the file opens with unwanted artifacts. Please see the image below. On the left is the ai file and on the right is the same file exported as .dwg and opened, with artifacts on the curves.
This is basic and shouldn't be happening in the first place. It makes working with manufacturing utterly painful.
Request you guys to please iron out this glitch.
Mac OS 15.3
Illustrator 29.2.1

Expected actually... That’s why it’s Export / Import and not Save / Open, conversion happens.
Bezier curves Ai uses get converted into splines DWG uses, and the conversion is not always an exact match...However, this needs investigating anyway. Please extract these objects into a separate .ai file, export it into .dwg, verify the behavior is still there when you import it back, and share all these, along with the export settings used: here (if UV would allow to attach the files, it can be too paranoid), or send them to sharewithai@adobe.com (and then mention the report’s permanent link: http://illustrator.uservoice.com/forums/601447/suggestions/49539077)
