Hello all,

I am a beginner with CityGML and am currently trying to convert a dataset to CityGML 3 with generics extensions using FME Workbench.

I re-organized the features in TrafficArea and added some new generic attributes. Then, I want to map these new features back to TrafficSpace to build the child-parent relation. But I always failed. I am not sure whether I used the wrong way to create the new TrafficSpace, and I didn’t find the tutorial online either. 

My workflow for the TrafficSpace is shown below. I extracted the boundaries from the TrafficArea and set them with lod2MultiCurve as the TrafficSpace back.

Welcome for any suggestions or assistance! Thank you very much.
