I'm trying to transform a Revit file, also using his IFC file, into a CityGML format file. After TestFilter is being used to get the different parts of the building, i have to preserve the hierarchy between the openings of the building, the walls and then the windows and doors.
At first i'm using the Openings as the requestor in the Transformer FeatureMerger and the result Walls from TestFilter as the supplier. Then the merge from the first transformer is being used as the supplier to a second FeatureMerger and the result from TestFilter, Windows_Doors, is set as the requestor.
The thing is, although i get all the possible merged features from the first FeatureMerger, the second will list all the features into UnmergedRequestor and UnusedSupplier.
Should i change anything in the geometry of the windows_doors factor or is it something completely different from what i'm thinking, that is actually missing?
