Thank you for your answer.
Yes, i already looked at all the available informations both from Esri and Autodesk.
We are studying a way to implement the informations of the overall building in ArcGisPro and then later in ArcGis Online, but we had problems in integrating those data in the 3D model because of the fact that Building Scene Layer Package d'ora not allow me to create It with a 'join' inside the data of the Layer.
I Guess the only way possibile Is to do a joint with the 2d shapefile of the Building.
