[Qgis-user] complete a polygon

[Randal Hale]

Tata,

You are referring to a tool that is comparable to autocomplete in the 
ESRI world. The closest I have gotten is the autotrace plugin (and it's 
not comparable - but it's closer to what you are looking for - 
http://www.lutraconsulting.co.uk/resources/autotrace). As for a process 
- the best (as far as I know and I hope I am wrong) is to digitize your 
work area as polylines - at the end convert them to polygons (vector -> 
geometry tools -> lines to polygons). It would save some clicking but 
would add a step (or maybe two).

Anyway - Good luck!

Randy
