Dylan: > Well from that 'angle' I think that it makes sense not to use > v.extrude. > v.points.to.3d seems like a fine choice. 'til now we have manged to keep the "."s in official modules to a max of two. see previous discussion: http://article.gmane.org/gmane.comp.gis.grass.devel/13714 http://article.gmane.org/gmane.comp.gis.grass.devel/13739 v.to.3dpoints or v.points.3d? It doesn't match v.to.rast,v.to.rast3 naming, but I think v.to.points3 would make it too close to v.to.points which is another task completely. But it is not so far from what v.to.rast3 does, so maybe not so bad. (shrug) to get a nifty instant prefab wrapper script do: v.transform --script Changing topic slightly, how about adding a -z flag to v.to.points for 3D lines?
