I have a full water supply network drawn in a shapefile which I created using Qgis 2.2.0. Now I need to export it into a format that enables me to open it in AutoCAD. I am trying to export it as a dxf file, but when I upload it in AutoCAD it shows an empty drawing (although the dxf file is 1.75MB). The shapefile is a line shapefile with several lines with a different main attribute (the diameter).
Maybe I have to save different dxf for each diameter?
