What is a key benefit of using the 'Link Revit' command?

The 'Link Revit' command is a valuable feature in Revit that facilitates collaboration among various project teams, making it the best choice. By linking different Revit models together, teams can work on separate aspects of a project—such as architectural design, structural engineering, and MEP coordination—while still integrating their work into a single cohesive model. This promotes a streamlined workflow, allowing for real-time updates and coordinated efforts without the risk of conflicting changes or overwriting each other's work.

Using this command fosters a more efficient design process, as it enables multiple stakeholders to contribute their expertise independently while ensuring that all elements remain connected and up to date within the overall project framework. This collaboration is critical in multi-discipline projects where various teams need to be on the same page, ultimately leading to better project outcomes.

In contrast, the other options do not accurately represent the primary benefit of the 'Link Revit' command. For instance, it does not specifically focus on the deletion of duplicate elements, does not inherently increase file size—though large linked models can impact performance—and does not prevent changes to original models, as linked models can still be modified by the originating team within their own projects.
