Hi all,

I report again a rounding problem, wondering why no one else seems to
have such problems.

Maybe someone con give me an good advice?

This time problem (see picture):
I have areas and lines and I want to remove the lines inside the areas-
I did:
-boundaries to lines ("arealines")
-patch lines and arealines
-break where they cross
-v.select -r -g operator=within
that should do, but due to ?roundings?, v.select does not do it
correct...(see picture) I would need a thresh in v.select, I guess,
hoping you might have an idea how to deal with it.

v.clean with snap does not work, because how can I tell the nodes at
line ends to snap to area boundaries.

Thank a lot in advance,
Achim
