[GRASS-user] 3D TIN?

[Carlos "Guâno" Grohmann]

Stefania,
do you really need to work with dxf files?  Are you using AutoCAD or
other CAD software? AutoCAD MAP can import shapefiles.
if you really need dxf, you can try to export as shapefile and then convert it.
there are some converters around, like:

http://www.globalmapper.com/
http://www.guthcad.com/arcv2cad.htm
http://www.mass.gov/mgis/dxf.htm

these are Windows programs, though.

good luck

Carlos
