[Gvsig_english] Question about Geoprocess toolbox: Topology errors correction in line vector layer

[Luigi Castro Cardeles]

hello,

topology errors correction in line vector layer. added gvsig 1.1.1 i think.

i want to break a line segment every time it intersect with another line.
the problem is that line self intersect at some point and i want to break it
at that point.
is the normal behavior of that geoprocess does nothing when a unique line is
self-intersect?
[]'s and thanks
