Using Worksharing with MEP Elements

Worksharing with MEP elements has been improved to enable better collaboration among team members and provide a more consistent experience across Revit.

Prior to Revit 2021, users may have experienced the following issues:

Starting with Revit 2021, there are two major changes to the behavior when you make modifications to the model. These changes apply to native Revit generic MEP elements and to MEP fabrication parts.

  1. When you move a run of duct, pipe, conduit, or cable tray, only the directly modified elements are checked out.
    Prior to Revit 2021, when you move a run of duct, pipe, conduit, cable tray, or connected equipment or fixtures, all directly or indirectly modified elements were checked out.
    In Revit 2021, only the directly modified element is checked out when you move a run of duct, pipe, conduit, cable tray, or connected equipment or fixtures.
    Important:
    • If elements are changed using an editor (change type, resize, etc.), then the elements that are indirectly changed may be checked out. For example, if you change the size of a pipe connected to a boiler, the boiler may also be checked out.
    • If new elements are added by one user and adjacent elements are modified by another user, there could be disconnects when either user synchronizes with the central model.
    • If the model contains fabrication parts and changes are made to the fabrication configuration, all users working in the model should sync with central and then close the model. The person responsible for making changes to the fabrication configuration must synchronize any changes, then reload the configuration before adding or removing any services.
    • If the model uses hosted elements, such as electrical panels or plumbing fixtures with a linked architectural model, elements may become disconnected when synchronizing with central if users have different versions of the linked model. To avoid issues with disconnected elements, all users must reload the linked model.
  2. When you delete an inline element such as a valve or damper, ducts and pipes are not automatically reconnected. Use the Trim/Extend command to reconnect two segments of duct or pipe.
