Blender Version
Broken: version: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb
Worked: unknown

Addon Information
Name: Export Autocad DXF Format (.dxf) (2, 2, 3)
Author: Remigiusz Fiedler (AKA migius), Vaclav Klecanda

Short description of error
Exporting to dxf goes wrong. The cause is the export is using the vertex index and if the vertex are not created in order the export result is messed up.

Exact steps for others to reproduce the error
Create a plane
Subdivide the edges
Export to dxf using polyface

I can confirm that the exported vertices order is basically the order the vertices are in the mesh.

But I'm not sure if this is a bug. If it were the order of the corners of the faces, the vertices would have to be repeated for each face that uses it.

Perhaps it is intentional that the mesh is converted to polyline considering only the existing vertices without repetition.

@RemigiuszFiedler, seems to be the author of the addon, if still active, he can better explain the situation and confirm if it is a bug.
