nokian [1] filed a deletion request for freecad-dxf [2]: The developer writes on github: "The files in this repository are not needed anymore when using the built-in DXF importer (default since FreeCAD 0.16). They are still needed if you wish to use the legacy python importer (settable in Edit-> Preferences -> Import/Export -> DXF) or if you wish to export directly from the 3D model (exporting a Drawing page to DXF also doesn't require these files)" [1] https://aur.archlinux.org/account/nokian/ [2] https://aur.archlinux.org/pkgbase/freecad-dxf/
