<p class="MsoNormal">I hope this email finds you well. 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.<o:p></o:p></p>
