In the Scene Viewer (and therefore also in the GeoBIM-App) the visibility of different scene layers interferes in an unpredictabel and uncontrollable way when using the building explorer: If one chooses a model for full model view with the building explorer, the other models are changing to default view (exterior shell) or are even vanishing completely. Unfortunately only with the building explorer it is possible to get the full model view (Architectural, and not only Exterior shell).
It should be possible to determine with the layers tab at any time, which models/layers are visibel as full model (not only exterior shell and without building explorer) at the same time. Only thus presentation, checking and comparison of a complex project is possible.
