Disable/Enable 3D Content and Authoring
The Disable/Enable 3D Content and Authoring setting allows organization administrators to enable users to upload, author, and view 3D content in Vuforia Editor. When this setting is enabled, Vuforia Editor authors can upload 3D models to Vuforia Editor and add models to procedures. By default, this setting is enabled.
For more information about working with 3D content, see 3D Models.
