[Qgis-user] Tolerance for topological editing

[Stepan, Carsten]

Dear community,

I have two polygon-layers in my map: "TopoLayer" and "Flurstück_edit". In order to maintain topology of these layers, I activated the "enable topological editing"-tool. However that somethimes creates strange situations, when features of my topolayer and my Flurstück_edit-layer happen to be very close to one another, but shouldn't actually share any geometry. In the image you can see two features from two different layers. Of course I could just deactivate the tool. But this isn't allways desired, as this completely destroys all kinds of topological behaviour - also between features of the same layer.

The scale is 5:1, so 5mm in the image is actually 1mm in reality:

The rubberband indicates that the two features are handled together. I already checked the snapping, which is off for both layers.

So regardless of any active snapping there seems to be some tolerance here that influences which features are handled together. But I wasn't able to find any documentation about this. Is there any (hidden) setting here?


Thanks for any help
Carsten
