[Qgis-user] QGIS lines to polygons takes a very long time!

[Jonathan Moules]

Hi both,
Give this, I’d suggest that the super-slow processing of the QGIS tool is a bug and worth reporting on the tracker if it’s not there already.
Cheers,
Jonathan

Jonas,

Thank you very much for your help and reply. I have used SAGA and it worked like a charm! :)

Best regards,
Ammar

Hi Ammar,
I was into the same problem some weeks ago, although with another tool, clipping. My experience was that the QGIS tool (found in the processing toolbox) required an incredible lot of time, however with correct result. So my advice is to try another tool for the calculation, i e SAGA or GRASS. You can read my mail correspondance by searching for 'Clipping tool takes a lot of time' in the mailing list. Hope this will help you out.
Best regards,
Jonas

Hello

I am running QGIS Chugiak on Windows 7 64 bytes machine. I am trying to run the Lines to Polygons geometry tool on a test data that contains 33 features (33 buildings) and the tool's progress bar is stuck on 26% for a couple of hours now! Is this normal? If not, what could be the reasons behind that?

Regards,
Ammar
