[Qgis-user] QGIS 3.22 - Geometry by expression howto

[Nicolas Cadieux]



Hi,

Try decimal with commas. Check your local system settings.  Could this be a wrong CRS problem?  Try zoom to layer extent to see if they pop up in the wrong place.  Share a few examples so we can check. Try  exporting the geometries to Wkt in a new field to see what happens….
