[Qgis-user] polygon segment

[Siki Zoltan]

Dear Jake,

you can use the topological editing. In Settings/Snap options dialog 
enable topological editing, check Avoid Intersections for the editing 
layer and optionally set a tolerance for snapping.
After it you have to draw only the missing part of the a new polygons.

Regards,
Zoltan
