We have been given a DXF that contains a Elevation attribute but we would like to generate a 3D DXF. I know I can generate a 3D dxf from a shapefile using:
ogr2ogr -f "DXF" out.dxf in.shp -zfield Elev
But the ogr driver doesn't seem to pick up the attributes as fields in the dxf.
Does anyone know if this is possible.
I would like a free solution if possible. We do have FME but I'm looking around for other options.
