Geoff,

Yes, definitely a raster.

GDAL does not support raster output to DXF or OBJ (as far as I know).
So you pretty much
need to fallback to some other DEM format.  You mention "DEM" which
I'd guess is likely
USGS ASCII DEM format.

You can try doing:

  gdal_translate your.adf -of USGSDEM out.dem

At the FWTools commandline.  This will produce a USGS ASCII DEM
file which might work with your software.  If you need to produce something
matching a particular product profile it is more involved, but in that case
read over:

  http://www.gdal.org/frmt_usgsdem.html

I presume you were actually doing the import and export from
within OpenEV?  I'd suggest doing the translation from the
commandline using gdal_translate as I vaguely suspect there
are limits on the capabilities of the OpenEV export tool.

Best regards,
