	We have written an extended version of v.in.dxf to convert some of
the layers in the AutoCAD DXF file into line vectors, and some into area
vectors. That should help. I was about to check with the Office of GRASS
Integration about testing this program and sharing it. If you need it in a
hurry, I could send you the files as I have.

	Another way to do it (the hard way) would be to import the file
with v.in.dxf into ascii line vector files, and then go in and edit the
dig_ascii and dig_att files to make them into area vector files. (Ref.:
GRASS programmers' manual.)
