OGR generated DXF files fail to work with FME

[warmerdam]

Reading a file generated with OGR in FME results in a message like "AutoCAD2004Reader::open: 'Not that kind of class'".

Further testing shows that at least some QCAD generated files also fail in FME.

I have found that if I switch to FME derived header and trailers for the DXF driver both FME and QCAD are able to read the files. Based on the error message, I *suspect* FME on windows is actually using components from autocad to read DXF and the problem might also manifest in some versions of autocad.

New trailer and header applied in trunk (r19773).

Andreas, can you test with the new header and trailer? You shouldn't really need to recompile. You can just grab:

 http://svn.osgeo.org/gdal/trunk/gdal/data/header.dxf

and

 http://svn.osgeo.org/gdal/trunk/gdal/data/trailer.dxf

and substitute them in your gdal data directory or reference them directly with the appropriate -dsco options to ogr2ogr.

Indeed, it seems to work now in FME and Autocad - this is great - thanks!
