I have a
.shp-file of some buildings with a sheet in an attribute table of their height. I want to extrude them using a Qgis2threejs plugin, but since a sheet of height is shown as a type of
QString, the plugin can't recognize it and the buildings can't be extruded.
I have tried to export a database as a
.csv-file, but the Excel is locked and it can't be modified.
Any alternative approaches?
