[Qgis-user] Node Tool not working

[Andreas Neumann]

 yes - that's right. The node tool is only for editing existing 
 geometries. Not to create new ones.

 Did you try the node tool on existing geometries or to add a new 
 geometry? If you want to add new geometries you need to use the "Add 
 Feature" Button in the digitizing toolbar. Once you added a new feature 
 (incl. the attributes) than you can start modifying it with the node 
 tool.

 You should also make sure that the snapping options make sense (if you 
 use snapping at all) - either set in map units (meters, feet, degrees) 
 or in pixels.

 Hope this helps,
 Andreas
