T,
To get the column length, you can use the export/add geometry function
in fTools, which will create a copy of the dataset (as a shapefile)
with an additional length field (or it will populated the length field
if it already exists). From this you can use the compute basic
statistics function to get the sum of the field...
Any chance to alter the fTools plugin so that the geometry functions
stick the new columns straight into the original shapefile? I can't
think of any situation where you'd need to keep both the original shape
without the geometry attribute and the new one with.
Other GIS software (i.e. GRASS as John Tull pointed out, as well as
Arc*) just add the length/perimeter, X-Y or area column into the
existing vector layer.
A minor annoyance, but it would be nice...
Thanks,
Micha
Hopefully that's what you are looking for?

HI everybody
i hope someone can help me with this:
in a poly-line vector layer, which is obviously built of several
festures, how can i add a column of LENGTH to the attribute table?
then how can i SUM all of it?
