When Select Links is turned off, Revit should also block elements from being hosted to linked models. At the moment, disabling Select Links prevents users from accidentally selecting links, but Revit still treats linked geometry as valid hosts when placing objects. This leads to elements unintentionally attaching to links instead of the active model.
Proposed Change
Extend the Select Links toggle to fully exclude links from interaction, not only selection. This includes preventing linked models from acting as hosts during element placement or modification.
