[Qgis-user] Import lines from cvs

[Joris Hintjens]

Thanks Nyall,

I try to understand your procedure, but…:

line3: “save as…”: Before doing that, I already need a geometry defined, a proces you describe later i the process. I don’t get it.
line 4: "- expand out the "Geometry” group…”  This is an option from the “load csv layer”, not from “save layer as (shape)”
line 8: change field to <geom>: which field?  I lost you there completely. Sorry.
