A linked model can be copied any number of times in a host project.
For example, a housing development may have multiple designs that repeat many times throughout the site.
For each copy of a linked model that you place in a project, a unique name is automatically generated. This name helps to identify elements from linked models in a schedule. You can modify the name for a linked model instance through its properties.
You can override visibility and graphics settings for each linked model instance. See Visibility of Linked Models.
You can copy linked models using the standard copy and paste procedures (see Copying Elements) or you can drag a linked model from the Project Browser into a project view.
In addition, you can copy a linked model between projects within the same Revit session. When you copy a linked model to another project, the link path, shared positioning settings, visible nested links, and the link instance name are copied to the new project. If the link instance name already exists in the project, the link is automatically renamed. Partially loaded files are maintained as partially loaded. Visibility and graphic override settings are not preserved.
