I have a revit 3d model and ik want it to import it in ArcGIS Pro or in AGOL webscene doe anyone have a suggestion
While not a great solution, you can export your Revit model to a DWG...and then ArcGIS can consume the DWG file.
A more complete solution involves IFC and the Data Interoperability Extension.
Someone recently marked my reply as helpful...but that reply was several years ago.
If you want to publish a Revit model to AGOL today, there is a much better way! Within ArcGIS Pro, you can add the Revit model into your map as a Building Layer. And from that, you can create the rich Building Scene Layer. For more detail, search the help documentation for information on how to create a Building Scene Layer.
