According to our Atlas expert,  Atlas GIS exports its dxf files
with blocks and GRASS cannot import blocked dxf files.  If 
autocad is available, you might try taking your dxf file into
autocad and re-exporting it without blocks.

Unfortunately the ascii route is also not straight forward.
Atlas exports the vector files with easting then northing
in the ascii vector file (should be northing, easting).
Also the header info is missing, and the L or A is some
other sort of label (or so I understand).  

There is currently no easy transport route that we know of,
does anyone else know of any?  

Nancy Thorwardson (nthorwar at is considering writing 
a script to convert the Atlas BNA file to the proper format 
for  If anyone has any existing alternatives, 
please let us know!
