[GRASSLIST:9588] v.buffer: area boundary around line? Wanted: howto!

[Wolfgang Qual]

Hi List,
I tried to create a new area boundary around a line theme. Thought it would
be easy to do it like this:

v.buffer in=ausschnitt out=buff_ausschnitt bufcol=gesamtbr type=boundary

But GRASS won't create a new theme. After that, I tried to first create a
line buffer theme (works fine) and then convert it to a area boundary theme
using v.type. However, the new area boundary theme does not have the shape
of the line buffer theme.

BTW, the line theme looks like this (street network):

  ------------------     
    |         |       ...but I get s.th.      XXXXXXXXXXXX
    |         |       like this:              XXXXXXXXXXXX
  --------------                              XXXXXXXXXXXX (area inside)

I would greatly appreciate to receive some hints...


Best wishes,
Wolfgang
