Thanks Markus and Hamish,<br>

Unfortunately v.clean rmdangle will not work for me. With
Threshhold<0 it deletes more or less all lines, otherwise none. I
guess it is because the "nests" of lines consist of 4-20 lines and are
all seperated from each other. <br>
Per defintion a line "is considered to be a dangle if no other line of
given <em>type</em> is on at least one end node" (documentation
v.clean rmdangle). As I am searching for lines that have exactly one
line as sum of all connecting node, this tool doesn't help.<br>
<br>
I will try to solve the problem by creating points out of the line
(nodes), buffering the points and delete the ones intersecting only one
line. But I still hope that there is a more direct solution to delete
the line as a geometry.<br>
<br>
So if there are any other suggestions I would be happy about. <br>
I'll keep you up to date in case I find a solution.<br>
<br>
Cheers, Patrick<br>

not a v.net specific thing, but in general for
vector maps you can use v.clean to remove (or isolate)
line "dangles" with the 'rmdangle' (or 'chdangle')
tools.
maybe that helps,
