Such confusion about such a relatively simple conversion!
The truth is that the data supplier need only ungenerate once, assuming
that he/she dumps all Arc attributes at that time.
The rub is that GRASS only allows one attribute at a time to be
associated with the polygons. Therefore, *on the user's side*, at the
time the file is imported with v.in.arc, the user will have to pick an
attribute, or, alternatively, create one GRASS layer per attribute.
I would not recommend the DXF conversion route. Many have reported
that attributes are lost with this technique.
