[Qgis-user] 3D analyst

[Nicolas Cadieux]

Hi,
Not sure what you are trying to do.

-If you are looking to extract contour lines from a DEM, use 
(Raster/Extract/contour) or Processing/Grass r.contour.step (with more 
options.)

-If you want to extract a terrain profile from a DEM, use Profile tool 
plugin.
-If you want to extract a terrain profile from a vector file (containing 
contour line), I believe the VoGis-ProfilTool Plugin, will do that (but 
never used it).  If that does not work, make a DEM with these contour 
lines using the Interpolation Plugin then use the Profile tool plugin.

To install plugins: Plugins/Manage and install plugins/All or not installed.
Good luck
Nicolas
