[GRASS-user] V.Select strange results

[Stefano]

Hi all.
i'm looking to v.select (grass 6.4).

i've 2 paths done by v.net.path, i want to extract the diff path of
these 2 paths using v.select, overlap and the reverse.
before this operation i clean both of them using break and snap.

As you can see in the image there are two path, one blue and one
green, these two path sheared pieces (u can't see the shared path,but
is not imporant).
so, i want find the differences of these two path.
i do the select with a reverse command but the result is not right as
i can excepted.

if u pay attention the black path (the diff path) is not completly
right. in fact this path has to start and finish on the intersection
of these two path (blue and green) but start and end before the
intersection. so the black path has to be identical as the green path
(the green path that u can see)

i think the problem is the lines of these 2 path (green and blue) that
are not cut in the intersection, so the line goes across the
intersection of these line.

how can i fix this problem?

thanks.
