There are many ways to share 3D GIS content – you can export videos and screen shots; you can set up a shared network drive; you can package and upload content online; you can publish 3D services; or you can publish views of your data as web scenes.
When sharing work with other ArcGIS Pro (3D Analyst) users, you can share your data and ArcScene/ArcGlobe documents directly, or upload layer packages to ArcGIS Online or Portal for ArcGIS.
When sharing interactive 3D views to people without Esri licenses, you can publish fully authored 3D views as web scenes, publish 3D services for consumption in ArcGIS Explorer (Desktop) and ArcReader, or export KML files for viewing in third-party applications like Google Earth.
Pre-authored 3D views, for use on websites or in publications, can also be exported as videos or screen shots from both ArcScene and ArcGlobe.
