Hello,

I'm want to sum up the length of all the streets in my community.
I have a vector file with the streetmiddlelines.
Under Vector there are the analysis tools and one of them is called 
"Lijnlengtes sommeren". It seems that this would be the right tool. When I open 
up the dialog and fill in the output file and select the streetmiddlelines, the 
tool complains that I haven't selected a vectorlayer as output. There is 
another dropbox where you can select a polygon vector layer (Why would you do 
that if you want to sum up lines?). If I select a polygon layer then the tool 
keeps running indefinitely. Seems that this is a useless tool, or am I doing 
something wrong?
