[Qgis-user] how to georeferenced an autocad .dxf file?

[Andreas Neumann]

 It would actually be very nice if the georeferencer tool in QGIS could 
 also handle vector layers. I would assume that much of the code from the 
 existing georeferencer could be re-used to also make vector 
 georeferencing work.

 I think it is annoying that one cannot easily transform vector data 
 usign a couple of match-points.
