I have a multi-patch layer in ArcGIS Pro 2.0 and I want to share the layer to ArcGIS Online. I cannot figure out how to save the multi-patch layer as a scene layer package. Under ArcGIS Pro Share tab, I can only see project, map, layer and geoprocessing package.
There is a Geoprocessing tool called Create Scene Layer Package and then you can upload that package to ArcGIS Online to create a Scene Layer. http://pro.arcgis.com/en/pro-app/tool-reference/data-management/create-scene-layer-package.htm
