Hi,
I am trying to write a CityGML file using FME Desktop 2017. I can write the Roof, Ground and Wall surfaces features which contain the geometries, however, the "Building" featureclass does not contain the HREF links to those surfaces.
This is easy to detect when using the inspector, as the Building featureclass does not show up as spatial.
I have set gml_parent_id in the surface classes, to the value of gml_id used in the building class.
