I want to change all the elevation of the polygons of a shapefile using the field value ELEV from each polygon. So each vertex of each polygons as all the same Z (elevation). Anyone knows how to do that?
Please

In QGIS 3.0, run the "set z value" algorithm. Hit the button next to z value and select the field containing your desired z values.
v.to.3d
in QGIS2.18, try (1) NOT to use a 3D polygon as the input. You need original 2D polygon with Z attribute field. (2) InAdvanced parameters
select area inv.out.ogr output type
