<p class="MsoNormal"><span lang="EN-US" style="font-family:"Tahoma","sans-serif"">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?<o:p></o:p></span></p>
