Linking Revit Models

You can link Revit Architecture, Revit Structure, and Revit MEP models. Linking Revit models is primarily intended for linking separate buildings, such as those that compose a campus.

When you link a Revit model into a project, Revit Architecture opens the linked model and keeps it in memory. The more links a project contains, the longer it can take to open.

Linked Revit models are listed in the Revit Links branch of the Project Browser.

You can convert linked Revit models to groups, and you can convert groups to linked Revit models. See Converting Groups and Linked Revit Models. You can also mirror linked Revit models. See Mirroring Elements.

When Should You Use Linked Models?

It is recommended to use linked models for

Linked models may also be appropriate for the following situations

In later stages of a project, it is generally not recommended to create a single building model with linked models due to the following

Linking Revit Models that Contain Links

When you import a Revit model that contains a linked Revit model, links become nested. You can show (or hide) nested linked models in the host model. By default, nested linked models are not visible in the host model.

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.

Nested links that are visible in the project display in the Revit Links branch of the Project Browser under their parent link. Nested links do not display in the Manage Links dialog.

Transferring Project Standards Between Linked Revit Models

If you open the host model, you cannot open the linked model in the same Revit Architecture session. However, you can transfer project standards from the linked model to the host model using the Transfer Project Standards tool. See Transferring Project Standards.
