Ronnie,
This is another AutoCAD format, and, as far as I know, there is no way to
import them directly into GRASS. You'll need to get your hands on a copy of
AutoCAD, where you can read these files, and then save them as dxf. Easily
done, *if* you have AutoCAD! 
Hi to you all
Today I received a bunch of vector files wich should have been in ascii dxf format. But these files are most cleary in a binary format with the extension DWG. Does anybody knows a way to import these files in grass.
Thanks
