I need to fill a hole in a multi-polygon layer on QGIS 2.0. I've set the snapping option for the layer as follows :
- mode: to vertex and segment
- tolerance 4 pixels
- avoid intersection "enabled"
- topological editing "enabled"
When I try to edit a rough shape around the hole and confirm it right clicking, the system told me "The feature cannot be added because its geometry collapsed due to intersection avoidance"
I have a multipolygon file with a hole. I'm not able to fill the hole because if I manually edit it the system tells me that it is impossible to add it because the geometry is collapsed due to intersection avoidance. If I try to use the specifc tool it tells me that it's impossible due to the snapping settings.
These are the images:
