• What permissions are needed to publish reality data? - ProjectWise ContextShare "Create" permission must be enabled for a user to be able to publish the reality data and the "Use" permission must be enabled for a user to able to display the reality data in an iTwin application.

• When reality data is published? - When a *.dgn file created in the Design application (Microstation, OpenBuilding Designer, or other) has local Point Cloud or Reality Mesh attachments, those reality data get Published by an iModel Connector.
• Where is reality data published? -  Reality data are converted to web-ready Tiles and uploaded to the ProjectWise ContextShare Service.
• How often is it published?  Reality data are static in nature and only published once. If new reality data are attached to a iTwin's *.dgn file, this reality data only will get published.
• Are there other ways to publish reality data? - Reality data can also be published to ProjectWise ContextShare using ContextCapture and Orbit 3DM.
• How does a reality data show up in the iModel? It is streamed into the iModel at the time we render it? - Visibility of reality data in iTwin applications is controlled by the Reality Data Widget. When visibility of a Reality data is ON, it gets streamed into the iTwin applivation. The Reality Data Widget will list all reality data that have been published to the iModel by a Connector (Attached) as well as all other reality data that are associated to the same iTwin as the iModel and overlap the iModel's geographic location.

Below are listed all  Methods to create iModels with Reality data.
