Update multiple scene objects

PATCH https://dev-api.bentley.com/scenes/{sceneId}/objects?iTwinId={iTwinId}

Updates multiple objects within a scene using an ordered list of atomic operations (limit is 100).

All operations are executed in the order provided. If any operation fails, all changes are rolled back.

Supported Operation Types

add: Create a new scene object.
- Objects will be validated based on user permissions and supported object types. See Scene Object Schemas Documentation for a full list of available object schemas.
update: Perform a partial update on an existing scene object.
- All properties are optional. The request payload should only contain the properties that you would like to update.
remove: Delete the specified scene object.
- If the object is a parent, any child objects will be unlinked. If the object kind is RepositoryResource, any associated styling objects will also be deleted.
