Dear Matt,
I've written an awk script to convert 3DFACE-s form dxf to a delimited
text file. Please find attached.
If you use Linux, start it in the shell like:
gawk -f 3dface2csv.awk Otway_Basin_Granites-gravity.dxf > result.csv
You can load the result.csv into QGIS az a delimited text layer with WKT
column.
Regards,
Zoltan

Dear Matt,
I've tested your dxf files in QGIS 2.0
Otway_Basin_curves.dxf loaded successfully (2D polylines)
Otway_Basin_Faults-basin.dxf not loaded, 3D faces are not suported by GDAL
DXF driver
Otway_Basin_Faults-shallow.dxf not loaded 3D faces
Otway_Basin_Granites-magnetics.dxf not loaded 3D faces
Otway_Basin_Granites-gravity.dxf not loaded 3D faces
You should find another way to import 3D faces from a dxf file.

Zoltan

Dear Matt,
which version did you try?
What type of entites your dxf file(s) contains? Are them supported by ogr
DXF driver? Check http://www.gdal.org/ogr/drv_dxf.html
Try to check entities with ogrinfo.
I had trouble with 1.8 (exspecially on Windows) to load dxf.
I used ogr2ogr instead QGIS, because you can set more options.
I cannot find any DXf file in the zip file you specify.
Best regards,
Zoltan

Hi group,
I'm trying to make sense of some DXF files.
these ones in particular
http://er-info.dpi.vic.gov.au/cgi-bin/download.pl?ID=3D_
models/3D_model_attributes.zip
there's also a 3D pdf model here..
http://er-info.dpi.vic.gov.au/cgi-bin/download.pl?ID=3D_
models/t009_OtwayBasin_3D.pdf
QGIS isn't able to open the dxf files, or it does but all I see is an
icon
called "entities" with no attributes. Ideally I'd be able to load these
as
rasters and make a few maps.
Any ideas?
thanks
matt
