I'm working with QGIS3 and I imported a CAD-File (.dwg). Now, its in Geopackage format, but I made somehow a mistake by importing it, cause I'm not able to work with the different layers. They are merged now.
All CAD-Layers are in one Geopackage and as I open the attribute table there are more than one layer in it. How can I seperate them from each other?
