Thanks Markus and Hamish,
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.
Per defintion a line "is considered to be a dangle if no other line of
given /type/ 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.
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.
So if there are any other suggestions I would be happy about.
I'll keep you up to date in case I find a solution.
Cheers, Patrick

perfect to delete the lines, or to search for the
nodes that link to more than one line.
I was searching in v.generalize, v.net,
v.to.point, v.to.db but won't find the proper
approach.
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,
Hamish
