Linked Models
Link models when individual buildings on a campus or different parts of a large building
reside in separate project files, or when each discipline works in its own edition of a
building model.
Read the following topics to learn about linking Revit models.

About Linked Models
Linking models is primarily intended for linking separate buildings, such as those that
compose a campus.
Workflow: Linked Models
The following is a typical workflow for using linked models. Your implementation may
differ depending on your project needs.
Linking Models
You can link models to more easily manage the individual parts or to improve
performance when working on a large project.
Workflow: Linked Models in Schedules
Visibility of Linked Models
Control the visibility of linked models and nested linked models in the host model.
Tagging Elements in Linked Models
When tagging elements in a view of a host model (C), you can also tag elements from
linked models (B) and nested models (A).
Linked Model Instance Properties
To see the properties of an element contained in a linked model, move the cursor over
the element in the linked model and press Tab to highlight the element. The properties
display on the Properties palette.
Linked Model Type Properties
To see the properties of an element contained in a linked model, move the cursor over
the element in the linked model and press Tab to highlight the element. The properties
display on the Properties palette.
Managing Links
If the source file of the link in your project has changed, Revit automatically updates
the link when you open the project.

About Linked Models
Linking models is primarily intended for linking separate buildings, such as those
that compose a campus.
You can link architectural models, structural models, and MEP models.
For example, the following site plan shows 4 building models linked to one model.
When you link a model into a project, Revit opens the linked model and keeps it in
memory. The more links a project contains, the longer it can take to open.
Linked 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 About Converting Groups and Linked Models. You can also mirror
linked Revit models. See Mirror Elements.

About When to Link Models
About Dimensions and Constraints in Linked Models
You can use elements in the linked model as references for dimensions and
alignment.
About Repeating a Linked Model in the Host Model
A linked model can be copied any number of times in a host project.
About Nesting Linked Models
When you link a model that contains other linked models, the links become
nested.
About Phases and Linked Models
When you link a Revit model that has more than one phase, phases in the host
model automatically map to phases in the linked model.
About Transferring Project Standards Between Linked Models
If you open the host model, you cannot open the linked model in the same
Revit session.
About Linking and Worksharing
If you enable worksharing, your links are contained in worksets.
About Directory Paths for Linked Models
A relative path defines the position of a linked file in a working directory such
as a project folder. Its position is defined by its relative location. An absolute
path defines the location of a linked file on a disk or network drive.

About Dimensions and Constraints in Linked Models
You can use elements in the linked model as references for dimensions and alignment.
For example, you can create a dimension between a wall in the host project and a wall in
the linked model. See Permanent dimensions and Aligning Elements.
You can also create constraints between elements in the host model and elements in a
linked model. For example, you can constrain a linked building to a property line in the
host model or a linked floor to a level in the host model. Linked models move as an
entire entity when the element to which they are constrained moves. Constraints on a
linked model (or an element in a linked model) only move the linked model, they do not
move elements in the host model. Constraints to links using shared positions are not
permitted.
Revit attempts to retain and rehost dimensions and constraints when you reload (or
unload and reload) a link.

About Repeating a Linked Model in the Host Model
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.

About Nesting Linked Models
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:
Overlay does not load nested models into the host model, so they do not display in the
project.
Attachment loads nested linked models in the host model and displays them in the
project.
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.
If you change the Reference Type setting for Project A (within its parent model, Project B) to
Attachment, when you import Project B into Project C, the nested link (Project A) displays.
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 View Filters for Linked Models.
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 Interference Checking.)
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. (See
Manage Links Dialog.)

About Phases and Linked Models
When you link a Revit model that has more than one phase, phases in the host model automatically
map to phases in the linked model.
When this initial mapping occurs, Revit maps phases by matching phase names.
You can manually set up a correspondence between phases in the host model and phases in the linked
model. To do this you set up a phase map in the properties of the linked model, and then apply the
phase map in the host model.
Note: Phase maps must occur in chronological order. For example, a phase map cannot be set up like
the following table. Since phase 1 occurs before phase 3, phase 3 cannot be mapped to phase 1.
Phase
Phase from linked model
Phase 1
Phase 1
Phase 2
Phase 2
Phase 3
Phase 1
Phase mapping is always maintained, unless phases in either the host or linked models are combined.
If phases are combined, the existing phase map of the remaining phase is used.

About Linking and Worksharing
If you enable worksharing, your links are contained in worksets.
If you update a linked file and want to reload the link, the workset in which the link is
located must be editable. If it is not, an error message appears indicating that the link
could not be updated because of the workset's non-editable status. See Make Worksets
Editable.
It is good practice to assign a team member to track links and be sure the appropriate
worksets are editable. After updating the link, the team member should synchronize with
central so that all team members have the updated link. See About Saving Workshared Files.
Also, you may want to create a workset exclusively for links, so that workflow is not
interrupted. See Setting Up and Managing Worksets.
For worksharing-enabled models, when in a local file, you can use the "Unload For me"
command to unload a linked Revit model for the current user only. This command works like
a permanent override and remains set for the user, for that link, until cleared with the "Clear
my override" command. The setting is stored in the central model, per user for each RVT
link. This command allows you to keep Revit links unloaded for portions of the model you
aren't working on, without affecting other team members. See Tools to Manage Links.

About Directory Paths for Linked Models
A relative path defines the position of a linked file in a working directory such as a project folder.
Its position is defined by its relative location. An absolute path defines the location of a linked file
on a disk or network drive.
Note: For a linked model that resides on a Revit Server, its position is defined by the Revit Server
link path type which replaces the relative or absolute path.
In general, you should use a relative path instead of an absolute path.
If you use a relative path and later move the project and the linked file together to a new
directory, the link is maintained. Revit tries to find the linked model by its relative position to
the working directory.
If you use an absolute path and later move the project and the linked file to a new directory,
the link is broken. Revit tries to find the linked model in the specified directory.
An absolute path may be preferable when you link in a workshared project, such as a central model
that other users need to access. This file is likely not to move from its location on disk.
In the following image, a simple directory structure is used as an example.
In this instance, absolute and relative paths are defined as follows. Note the folder Working
Directory. This has been named as such for illustrative purposes. A working directory can possess
any name.
File
Absolute Path
Relative Path
sourcefile.rvt
C:\My Revit\Working Directory\source-file.rvt
source-file.rvt
file_01.rvt
C:\My Revit\Reference\file_01.rvt
..\Reference\file_01.rvt
file_02.rvt
C:\My Revit\Working Directory\Support
Files\Detailing\file_02.rvt
Support
Files\Detailing\file_02.rvt
If the working directory is moved or renamed, paths can become unresolved (broken). In the
following image, the working directory has been moved to the My Documents directory to illustrate
this.
Now all of the original absolute paths are unresolved because they point to a specific location. The
relative path to file_01.rvt is also broken as it resided outside of the working directory and didn't
move with it.

About Adding Links that Require an Upgrade
When you link a Revit model to the current model, a message displays if the linked model needs to be
upgraded to the current software release.
The message indicates the software release of the model and the release to which it will be upgraded.
Depending on the size of the model, the upgrade process can take some time.
If you do not want to upgrade the model that you selected for linking, click Cancel Upgrade. The model is not
upgraded, and it is not linked to the current host model.
If you proceed with the upgrade, the changes to the linked model are temporary; they are not saved when
you save the host model.
To permanently upgrade the linked model, you must close the host model and then open, upgrade, and save
the linked model. The next time that you open the host model, the linked model will not require an upgrade.
Important: Revit models are not backwards-compatible. After a model has been upgraded and saved, you
can no longer open the model using the earlier release of the software.

Transcript
When you collaborate on a project, you can linkRevit files to each other to manage
individual models or to improve software performance. ​With linked models, you can
coordinate the design across multiple models and disciplines.
On the insert tab, use the Link Revit tool to add a linked a model into the host model. ​In
most cases, you should select Auto - Internal Origin to Internal Origin for positioning. ​If
the host model and the linked model have already been set up to use shared coordinates,
use Auto - By Shared Coordinates. ​The Shared Coordinates option aligns the coordinate
systems of multiple linked files.
​ inked Revit models are listed in the Revit Links branch of the Project Browser. If a linked
L
model in your project is changed, Revit automatically updates the link each time you open
the host model. ​If you need to update linked models while working on the host model, you
can use the Manage Links tool to reload the linked models.
You can control how linked models display in all views or only in specific views. ​You can
also tag elements from linked models. ​The tags exist in the host model only, not in the
linked model.
Linking allows you to work in a coordinated and collaborative way across multiple models.

(Link Revit).
3. In the Import/Link RVT dialog, select the model to link.
Note: If you are using Revit Cloud Worksharing, you can only link to a model in the
current cloud project.
4. For Positioning, specify the desired option.
In most cases, you should select Auto - Origin to Origin.
If the current model uses shared coordinates, select Auto - By Shared Coordinates. See
Shared positioning.
See Positioning for Imports and Links.
5. Click Open.
If you cannot see the linked model in the drawing area, do the following:
1. In the view properties, for Discipline, select Coordination.
This setting ensures that the view displays elements for all disciplines (architectural,
structural, mechanical, and electrical).
2. (Optional) To display the linked model in halftone, for Visibility/Graphics Overrides,
click Edit. On the Revit Links tab, for the linked model, select Halftone, and click OK.
You can select the linked model in a view and drag, copy, paste, move, and rotate it.
Both the Project Base Point and Survey Point from the linked model are visible to help you
align coordinate systems between models.
You can also monitor grids, levels, and other essential elements in the linked model. See
Multi-Discipline Coordination.

Workflow: Linked Models
The following is a typical workflow for using linked models. Your implementation may differ
depending on your project needs.
To link models
1. Create a project for each individual piece of the larger project.
For example, for a campus, create a separate project for each campus building. For a large
building, create a project for each separately managed piece of the project. If a large building
has 2 towers, for instance, create a separate project for each tower.
2. Create another project to act as the main project that will link to the other projects.
3. Open the main project, and link in the projects containing the individual pieces.
See Link One Model to Another.
4. Place the linked models in the desired positions.
When you link models to the main project, you can share the coordinates of the project so that
you can correctly position the model. See Shared positioning.

Reposition a Revit Link
Reposition a linked Revit model after it is inserted.
Two options are available to reposition an instance of a linked Revit model after it is
inserted: Reposition to Internal Origin and Reposition to Project Base Point. These options
are available for any linked Revit model regardless of the original positioning method used.
1. In the drawing area, select the linked model instance, right-click, and click one of the
following options:
Reposition to Project Base Point: Positions the RVT link using the model's Project
Base Point as the insertion point, and aligns it to the Project Base Point in the
host model.
Reposition to Internal Origin: Positions the RVT link using the model's world
origin as the insertion point, and aligns it to the internal origin in the host model.
2. If the orientation of the linked model was changed after it was inserted (rotated or
mirrored), then you are prompted to choose one of the following options:
Preserve Orientation: If you select this option, the current orientation of the link
instance is retained when the model is repositioned.
Reset Orientation: If you select this option, the original insertion angle of the
link instance is restored when the model is repositioned. Any adjustments to the
orientation are cleared.
Here are a couple of scenarios where it may be helpful to preserve the orientation:
Your model is a campus plan where some buildings are identical. To achieve this
design, some link instances have been copied or mirrored. If you had to move the
position of one of the RVT link instances, you may not want to lose the
orientation you applied. By selecting to preserve orientation you can maintain
the adjustment and still reposition the link instance.
After creating several instances of a RVT link, you have set all of the instances to
a specific rotation angle. You need to reset the location of the link instances, but
you don't want to re-rotate every instance back into place. The preserve option
allows you to keep the angle while fixing the location back to the original
placement origin point or project base point.
