Dear Carlos and all,
I tried the export via shapefile too, as I do actually have Autocad Map.
The problem remains the same. For some reason (or actually, probably the
same reason highlighted my Markus in previous correspondance) the v.out
even in this case does not transfer 3D info.
I really need to work in 3D to edit these TINS and create a 3D geometry to
then import in GRASS and Paraview. Can anybody assist? I am basically
trying to create 3D irregular volumes from points to represent
archaeological features.
Yours,
stefania

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

Thank you Markus for the clarification.
Is there anybody out there that could assist the support for 3D face? I
cannot program...
