[Qgis-community-team] Topological errors - cutting and merging polygons

[Clemens Holzer-Salcher]

Dear QGIS community,

I hope you can help me.
I keep having problems editing polygons, more specifically, cutting and merging polygons. Often, after cutting and merging, line structures and other geometric imperfections remain, even with topological editing enabled. In some cases, deleting individual vertices helps to make the lines disappear, but in other cases, deleting a vertex distorts the polygon. Either way, it's quite tedious, especially when you want to split and merge many polygons. Why does this happen, and how can it be avoided?

Best regards
Clemens
