DXF export in the latest development snapshot produces possibly incorrect files

[JanKalin]

Using the latest development snapshot, 2022.05.15.ci11888 (git 6aae79634) on Windows 10, the DXF files are apparently incorrect. Steps to reproduce:

• Create a simple script that produces a square: square(10);
• Render with F6 and export with File|Export|DXF
• Load into Autodesk's DXF viewer https://viewer.autodesk.com/designviews

The viewer complains that the file is invalid:

Repeating the same steps with the stable version 2021.01 works OK. Possibly the problem is in the Autodesk's viewer, but a colleague of mine also tried importing it into CorelDraw and it failed. I've attached the two files produced by different versions.

Square_DXF.zip

It would help if there's also a recovered version of the file, assuming that works as mentioned in the screenshot.

I absolutely agree. But I don't have access to AutoCAD or I would have tried it. Perhaps someone with access can try - the file is Square_developer_snapshot.dxf in the attached ZIP.

Square_release.dxf is four separate lines according to InkScape but Square_developer_snapshot.dxf is a single path that is a square.

Yes, the change for that is #3869.

I built from source at the development tip and stepped on this, I suspect. Uploading the DXF to SendCutSend crashes the website, the part has no preview.

I haven't bisected this yet. Could be #3869.

Last known working release for me is 2021.01 (sorry). The failed release is from github, reports itself as 2023.11.11.
