Hi,
As far as I know last year it was possible to assign an offset to a scene layer. this scene layer
workflow:
1. revit model --> scene layer package
2. publish to AGOL and add to a global scene
3. add offset to the scene layer because a revit model has not always assigned all the coordinate system properties
A workaround could be to assign a cartographic offset in ArcGIS Pro and then create the scene layer package but the possibility to assign a cartographic offset for a Revit model is greyed out:
