Upload of data to PW ContextShare is enabled through its API as well as using Desktop client applications.
The creation of Reality Data in format optimized for streaming must be done before uploading it.
Depending on the workflows expert users may prefer to use different products/tools for these tasks such as iTwin Synchroniser & connectors, ContextCapture or Orbit Content Manager. However, if you are looking for a repeatable method (for data types & different projects) the best practice is to optimize for streaming & upload Reality Data on PW ContextShare at the beginning of the project and to use Orbit free Upload tool to tackle these 2 tasks.
Reality Data can then be consumed directly in iTwinJS applications and Design applications from PW ContextShare and most of the time as real time streaming.
