When you link a model that contains other linked models, the links become nested. You can show or hide nested linked models in the host model. The nested links display according to their Reference Type setting in the parent model:
The following image shows that Project A is linked into Project B (so Project B is the parent model for Project A). The Reference Type setting for Project A is set to Overlay within its parent model (Project B). When Project B is imported into Project C, Project A does not display.
When a nested model can display in the host model, you can indicate whether the nested model displays in a view using a filter from the host model, the filter applied to a view in the linked model or the nested model, or no filters. See .
When a nested link is visible, you can use Tab to select nested link instances and view properties of elements in the nested link, as you can with other linked models. In addition, the Interference Check tool checks for interference in the nested linked models as well as the parent linked model. (See .)
