3D Linestring in geojson leads to corrupted dxf file

[renderflash]

When converting a geojson with a 3D Linestring in it to a dxf file, the output seems to be corrupt (DWG TrueView returns: Two vertices were added to a 2D pline (0) which had no vertices.). When converting the same geojson to a shapefile everything works perfectly. Command used: ogr2ogr -f "DXF" outfile.dxf infile.geojson I used the daily trunk snapshot from the 25th of august.

renderflash,

I've perhaps a fix. Could you test the attached out_after_ticket5217_patch.dxf that is the result of the conversion with with trunk + ticket5217.patch applied ?

For the out_after_ticket5127_patch.dxf I now get the error: "The following error was encountered while reading in VERTEX starting at line 1566: Class separator for class AcDbEntity expected"

Hum, ok I'm attaching a new attempt as out_after_ticket5217_v2_patch.dxf . Can you test it ? Thanks

I believe you're getting closer! This is what I get now: "The following error was encountered while reading in SEQEND starting at line 1646: Class separator for class AcDbEntity expected"

Thanks for your patience... Hopefully the attached out_after_ticket5217_v3_patch.dxf will be the good one

[renderflash]

Well, thanks for your time to fix this. And indeed it is fixed now! Great work!
