Revit Worksets and Worksharing: Central vs Local Models

Large Revit projects often involve architects, structural engineers, MEP designers and BIM coordinators working on the same model. Without a collaboration strategy, simultaneous edits can create conflicts, delays and inconsistent project information.

Revit worksharing provides a controlled method for sharing model changes. It combines a central model, local working copies and worksets that help organize model elements.

1. What Is Revit Worksharing?

Worksharing is Revit's collaboration system for allowing multiple users to work on a project model. Each team member works in a local copy and exchanges changes with the central model through synchronization.

The central model acts as the shared source of project data. Users do not normally edit the central file directly during everyday work. Instead, they make changes in their local models and synchronize them with the central model.

2. Central Model vs. Local Model

A local model lets a user make changes without constantly modifying the shared model after every action. Synchronization sends the user's changes to the central model and receives relevant changes made by other team members.

3. What Are Worksets in Revit?

Worksets are collections of model elements used to organize a workshared project. They can help teams divide responsibility, manage visibility and control how parts of a model are handled.

For example, a project might use worksets for:

• Architectural elements
• Structural elements
• Mechanical equipment and systems
• Electrical components
• Levels, grids and shared reference elements
• Linked models and project-specific coordination content

Worksets should reflect the actual coordination needs of a project. Creating too many worksets can make administration harder, while creating too few may provide insufficient control.

4. Synchronize with Central: How It Works

Synchronize with Central is the main operation used to exchange changes between a local model and the central model.

1. Open the correct local model.
2. Make and save your project changes.
3. Use Synchronize with Central to send your changes.
4. Receive changes that other users have synchronized.
5. Review any warnings or conflicts reported by Revit.

Synchronizing regularly reduces the amount of unsynchronized work and helps the team stay aligned. The appropriate frequency depends on project size, network conditions and team workflow.

5. Element Ownership and Relinquishing

In workshared projects, users may borrow elements or obtain ownership of worksets. This prevents conflicting edits to the same model content.

When a user no longer needs control over borrowed elements or worksets, relinquishing makes them available to other team members. Synchronizing and relinquishing are related but different operations: synchronization exchanges model changes, while relinquishing releases ownership.

Avoid keeping ownership longer than necessary. If another user cannot edit an element, check whether it is borrowed or belongs to a workset controlled by someone else.

6. Common Revit Worksharing Problems

Cannot edit an element

Another user may own the element or its workset. Check ownership information and coordinate with the person currently controlling it before attempting to make changes.

Local model is out of date

The central model may contain changes that have not been received by the local copy. Synchronize with Central and review any conflicts or warnings.

Synchronization takes too long

Large models, network latency, extensive changes and linked content can affect synchronization time. Keep models organized, avoid unnecessary detail and follow a consistent team workflow.

A local model cannot connect to the central model

Check the central model location, network access, file permissions and whether the project has been moved or reorganized. Do not casually replace or overwrite a central model to solve a connection issue.

7. Best Practices for Multi-User Revit Projects

• Establish a clear central model location.
• Ensure every team member creates and uses the correct local model.
• Define worksets before the project becomes difficult to manage.
• Synchronize regularly and communicate before major changes.
• Relinquish borrowed elements when they are no longer needed.
• Keep backups and follow the project's file-management rules.
• Document procedures for model recovery and team handovers.

Frequently Asked Questions

What is the difference between a central and local model in Revit?

The central model is the shared project model. A local model is the user's working copy, which exchanges changes with the central model through synchronization.

Do I need worksets to use Revit?

Worksets are part of Revit worksharing. A project that does not require multi-user worksharing may not need a workshared setup.

What does Relinquish All Mine mean?

It releases ownership of elements and worksets currently owned by the user, making them available to other team members when the changes and project state permit it.

Can multiple users edit the same Revit model?

Yes. Worksharing allows multiple users to work on a shared model through local copies, ownership controls and synchronization. The team still needs clear coordination rules.
