[Qgis-user] Running v.clean on a QGIS vector layer (Polygon) through Sextante

[Bernd Vogelgesang]

Just retried it, and it seems to work now.
A month ago, it definitely didn't. I tested it there myself, to no avail:  
http://gis.stackexchange.com/questions/54388/grass-v-clean-snap-with-polygons

Ok, Sextante seems to have changed a lot recently and i have to admit that  
i lost the overview.
Just another question: From the GRASS toolbox with v.in.ogr there is the  
possibility to convert line features to boundaries while importing. This  
seems not to be implemented with in Sextante so far, right?

It seems that v.edit tool=chtype does that too (or is utilized through the  
advanced options of v.in.ogr), but it's not available through the toolbox  
directly nor through Sextante ...

Just my 2 and 1/2 cents,

You guys will be doing whats right, I'm sure!
Over and out
Bernd
