Is it possible to visualize LOD2 data in QGIS?
I`d like to find out if and how it is possible to visualize LoD2 data (source: https://www.opengeodata.nrw.de/produkte/geobasis/3d-gm/) in QGIS 3.4/Madeira. So far I managed to load them into the project, but unlike other examples and tutorials I´ve seen, they come as lines instead of polygons.

How to merge building outline layers in QGIS?
Use the Merge Vector Layers tool to combine the original building outline layer with the new layer you created in the last step (be sure not to choose “selected features only” for this step) Use the Dissolve tool to combine the original building outlines with the new line segments, using the unique building ID field as the Dissolve field.
Which is the best setting to use in CityGML?
There are three options: Absolute, Relative and Terrain. Depending which setting you choose, height values are interpreted differently. The Absolute setting is the best if height values are absolute and measured from 0 (like in a CityGML example). Two other values, Relative and Terrain, add given height values to terrain elevation.
