Dear all dear Markus,
Above all great job GRASS dev team ! Grass 7 is so nice and powerful.
I'm always in the dark with my dams problem.
I would like to export dams points as node and for each node in the
attribute table 2 new column : dam before | dam after. I'm looking for
network analysis but it may be a wrong way ?
There is a way to do that in Grass?

(I guess that you need to set "type=line" and not "type=point")
... this is why you may consider to upgrade to the current 7.0.x stable
version. Note the differences:
https://grass.osgeo.org/grass64/manuals/v.out.ogr.html
type=string[,string,...] Feature type(s).
Combinations not supported by all output formats. Default: first type
found in input.
Options: point,line,boundary,centroid,area,face,kernel,auto
Default: line,boundary
https://grass.osgeo.org/grass70/manuals/v.out.ogr.html
type=string[,string,...] Feature type(s)
Combination of types is not supported by all output formats.
Default is to use first type found in input vector map.
Options: point, line, boundary, centroid, area, face, kernel, auto
Default: auto <<==
Less to think about, much faster vector data processing, improved
network analysis along with new graphical frontend:
