Worksharing and Linked Models for Multi-Discipline Coordination

What Is Worksharing?

When a Revit project is small and only one person works on it at a time, a single project file is enough. Real manufacturing facilities and marine vessel projects, however, involve architects, structural engineers, equipment designers, and piping specialists all working simultaneously. Revit's Worksharing feature solves this by converting a single-user file into a Central Model stored on a shared network location or Autodesk Construction Cloud. Each team member works in their own Local Copy, edits elements they need, and periodically Synchronizes with Central to push changes up and pull everyone else's changes down.

Worksharing does not require expensive server software. A mapped network drive that all workstations can reach is sufficient, though cloud-based collaboration through BIM 360 or Autodesk Construction Cloud adds version history and access control.

Enabling Worksharing

You enable Worksharing once, from a regular Revit project file, before placing it on the shared drive. The steps are:

1. Open the project file on your local machine.

2. Go to the Collaborate tab and click Worksets.

3. When prompted, click OK to enable Worksharing. Revit automatically creates two default worksets: Shared Levels and Grids and Workset1.

4. Rename or add worksets to match the project disciplines — for example, Architecture and Structure.

5. Choose Save As and save the file to the shared network folder. This copy becomes the Central Model. Do not open or edit the Central Model directly after this point.

Each team member then opens the Central Model and, when prompted, chooses Create New Local. Revit places a Local Copy on that person's workstation. All editing happens in the Local Copy.

Worksets and Element Ownership

A Workset is a named collection of elements. When you make an element editable (by clicking the pencil icon or using the Editing Request tool), Revit grants your user name ownership of that element. Other users can still view it but cannot modify it until you release it. This prevents two people from editing the same wall or beam simultaneously and creating a conflict.

Good practice is to keep worksets broad and disciplinary — one for Architecture, one for Structure, one for MEP — rather than creating dozens of tiny worksets. Too many worksets slow file performance and complicate coordination.

Synchronizing with Central

Synchronize with Central (SWC) is the command that uploads your edits to the Central Model and downloads everyone else's. Use it frequently — at minimum before you leave for a break or at the end of the day. The Worksharing Monitor is a small companion tool that displays who is currently synchronized and who has unsaved local changes. Reviewing the Monitor before a synchronization helps you anticipate conflicts.

If two users have edited the same element (a conflict), Revit flags it. The user who synchronizes second is asked to accept or reject the conflicting change. Communicate with teammates before editing shared boundary elements like exterior walls or primary structural grids.

Linked Models for Multi-Discipline Coordination

Even with Worksharing, it is common for separate disciplines to maintain entirely separate Revit models — for example, the MEP (mechanical, electrical, plumbing) team may deliver a standalone `.rvt` file. You connect that file to your architectural Central Model using Manage Links on the Insert tab.

The critical setting when linking is positioning. Choosing By Shared Coordinates ensures the MEP model snaps to the same real-world origin as the architectural model, so ductwork and pipe runs appear in their correct physical locations. If shared coordinates have not been set up, use Auto – Origin to Origin as a fallback and coordinate with the other discipline team to establish shared coordinates afterward.

After linking, use Visibility/Graphics (shortcut VG) to control how the linked model displays in each view. You can show or hide the linked model's categories independently of your own model's categories. This is particularly useful in marine drafting, where machinery space models and hull structure models must be overlaid for clash checking.

Clash Detection and Coordination Review

With the linked MEP model visible in the architectural model, you can perform a visual coordination review. For formal clash detection, Autodesk Navisworks is the standard tool, but Revit's own Interference Check (found under the Collaborate tab) can identify basic geometric intersections between elements of the host model and a selected linked model. Run Interference Check after major design changes and log results for the coordination team.

File Management and Network Safety

Because multiple users share a Central Model file, safe file-handling practices protect the whole team:

• Never cut, copy, or move the Central Model file using Windows Explorer while others are connected. Use Revit's own Save As workflow.
• Back up the Central Model folder daily. Revit saves automatic backups alongside the Central Model, but these can be deleted accidentally.
• Label folders clearly: `ProjectName_CENTRAL` vs. `ProjectName_Local_YourName`.
• On shared network drives, apply folder permissions so only authorized team members can write to the Central Model folder. Accidental overwrites by someone outside the team can corrupt the file.
• If your workstation crashes while you hold editable elements, another team member with Owner-level access can relinquish your elements from the Worksets dialog so work can continue.

Connection to Industry Practice

Worksharing and linked models are the backbone of BIM coordination on commercial shipbuilding projects and large manufacturing plant designs. Classification societies and shipyard owners increasingly require coordinated BIM deliverables as part of the design approval package. Proficiency with these workflows is directly tested in the Autodesk Certified Professional exam and is a daily expectation in any multi-discipline Revit office.
