Loading 3DML Exposed as I3S in Esri Clients
After a 3DML is published to SGS, in addition to streaming the layer to remote TerraExplorer clients, SGS also exposes the layer as I3S for all Esri clients, i.e., ArcGIS Earth, ArcGIS Pro and ArcGIS Online. SGS supports I3S/SLPK 1.5 and 1.7. SGS exposes a layer as I3S 1.7 if the 3DML was published to SGS by TerraExplorer 7.3 or higher. The I3S versions that are supported for a layer are listed in the General section of the Layer Properties dialog box.
Only simple mesh layers can be loaded. Classified mesh layers, model layers that were converted to 3DML, and BIM layers are not supported.
