Hi Klaus, Just a guess: the only snap to grid thing I know about is https://docs.qgis.org/3.22/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#snapping-on-custom-grid. Worth a check? Regards, Harrissou Le 28/06/2022 à 15:54, Klaus Mithöfer via Qgis-user a écrit :

[Qgis-user] Simplify geometry - snap to grid
