[GRASSLIST:5677] big problem

[Carlos Henrique Grohmann de Carvalho]

Hi all,
 

 
I was wondering: how could I start with a drainage map (2d, imported from 
arcview), and end with a 3d map, where every vertex has a z-attribute? Is 
that possible within GRASS? I was thinking in convert it into raster (one 
category only, value=1), multiply with a DEM and convert it into vector 
again. Problem lies in mantaining the z-value, and a unique ID for each 
line.
 

 
any help will be very important.
 

 

 
thanks
