Hi, By reading the documentation https://gdal.org/drivers/vector/dxf.html#dxf-writer what you see is expected. --config DXF_WRITE_HATCH FALSE is writing polylines and polylines have vertices with different Z coordinates. --config DXF_WRITE_HATCH TRUE writes polygons. The polygons have same elevation value at each vertex, and that is also documented: “You may need to do this [to use DXF_WRITE_HATCH FALSE] if your geometries do not have a constant elevation, as the DXF HATCH entity cannot represent such geometries.”

I'm encountering an issue converting 3D GeoJSON polygons to DXF format using ogr2ogr. During conversion, the elevation data becomes uniform for all points within the polygon. Additionally, when using "DXF_WRITE_HATCH," the geometry becomes a polyline instead of a polygon. Attached are the GeoJSON data and conversion code for your reference. Could you please assist in resolving this discrepancy? ogr2ogr -f "DXF" output.dxf input.geojson -t_srs EPSG:32737 --config DXF_WRITE_HATCH FALSE Thank you for your attention to this matter. -- Saygılarımla / Kind Regards Shahrukh Mirza NAWANDISH Havacılık Bilgi Sistemleri / Aeronautical Information Systems Yazılım Geliştirme Uzm.
