The Selection tab allows you to specify individual objects to generate.
By default, all the objects in the model except for those that belong to a package, or that are shortcuts from another model are listed and selected for generation.
You can save your selection via the Selection bar at the bottom of the tab. For more information, see Quick launch selection and settings sets.
For more information about Selection windows, see "Adding an item from a selection list" section in the Objects chapter of the Core Features Guide.
