Dear community,
I would like to create a cityGML file from a db, which structure I don´t know. I have found a table, where building parts like in the picture are saved as polygonz, but I can´t aggregate them into one solid.
The _geometry field I got from an GeometryExtractor, because there was no possibility to see the geometry attribute in the FeatureReader.
Is it possible to aggregate those faces into one solid?
