Hi all.
I have a problem with v-edit.
I have to break a vector line
into two parts near a point. I gave this command:
v.edit map=ret_125
layer=1 type=line tool=break thresh=$ris_edit coords=$x,$y snap=no
where " $ris_edit " depends on the resolution of the DEM raster map,
"$x" and "$y" are
I can't figure out how to solve a problem with a line feature shapefile I
have. It has been wrongly created as 81 single lines touching each other
with their vertexes. I need to merge the lines into a unique line. I've
tried with v.edit and the merge tool, two times. First time it gave me 32
lines,

Ok I found out the problem meanwhile you were answering. I had 4 lines but
three of them where very weird: 2 points, vertex to the same vertex -> a
point, but stored as a line. I couldn't see it, beacuse it was superimposed
on the major, single line.
I think it was a problem with the original shape

so should I understand that result of tool=select no feature is found?
Can you send me sample data?
