Recently I upgraded my qgis from 2.6.1 to 2.14.9. In the old version I used the tool 'polygonize' (not the plugin!) to transform lines into polygons. The results were always very good. Sadly, this tool no longer exists in the 2.14 version. Instead there is the 'lines to polygons' tool. However, this new tool does not seem to work properly. I did some tests with line layers which I had succesfully transformed into polygons in v2.6 but in the new version I do not get the same result! See the difference in results below:
I did some research and I see that more people are struggling with the lines to polygons tool. Is there a way to get the old polygonize tool back or is this problem resolved in more recent versions of QGIS?
