Synthèse
The SceneLayerSharingDraft class allows you to create a sharing draft for a web scene layer with an associated web feature layer. You can configure the SceneLayerSharingDraft object for a web scene layer that copies all data or references registered data to ArcGIS Enterprise, or copies all data to ArcGIS Online.
The object can publish the following types of scene layers:
- Point
- 3D object
- Building
To publish a web scene layer cached locally in Python, use geoprocessing tools instead. For more information, see Publish web layers using packages.
Discussion
To create the SceneLayerSharingDraft object, use the Map object's getWebLayerSharingDraft method and set the service_type parameter to SCENE_LAYER. To specify whether the web scene layer copies all data or references registered data to ArcGIS Enterprise, set the server_type parameter to one of the following:
- HOSTING_SERVER—Copies all data; an associated web feature layer is included.
- FEDERATED_SERVER—References registered data; an associated map image layer and web feature layer are included.
Additionally, the layers_and_tables parameter in the getWebLayerSharingDraft method must be a list with a single layer. Use the listMaps function from the ArcGISProject object and the listLayers method on the Map class to reference the layer in the 3D scene you want to publish.
The SceneLayerSharingDraft object can then be configured by setting service level properties. You can also set properties on the SceneLayerSharingDraft object for the associated web feature layer and map image layer. If no value is specified for a property, the default value is used. Information about each property is provided in the Properties list below.
Remarque :
If metadata properties (credits, description, summary, tags, and useLimitations) are not set or consist of empty strings, the web layer item will source metadata from the scene layer in the ArcGIS Pro project, depending on what is shared. For more information about how web layers source metadata, see Web layer metadata.
After the SceneLayerSharingDraft object is configured, it can be analyzed for errors and warnings using the optional analyzeForSharing method, and published using the Publish function. The Publish function publishes the web scene layer and any associated web layers to either ArcGIS Online or ArcGIS Enterprise, and starts caching on the server.

The following script creates a web scene layer sharing draft for a layer in a scene and sets metadata and folder properties. The web scene layer is published to a folder in either ArcGIS Online or ArcGIS Enterprise and shared with everyone (public). Portal information is obtained from the SignInToPortal function.
