How can I upload my 3D buildings and Bridges into the ArcGIS online Scene Viewer? (Such as in The Netherlands example in the scene builder?) I have them as multipatch, Collada, or .3ws...but I cant seem to add them as a layer in a scene. I currently use the CE Web Viewer, however I want to use the Scene Viewer because of its usefulness in the Story Map Journal, but I want to use my 3D objects in the scene.
