Use worksharing to allow multiple users to work on different parts of one Revit project.
Worksharing allows simultaneous access to a shared model through use of a central model. Use worksharing when you are working with a single model (one RVT file) that will have multiple team members working on it.
Using linked models, project elements or systems are separated into individually managed models that can be linked together. Use linked models when your project contains distinct buildings, such as a campus, or when you are working with team members from other disciplines, such as:
You can also use worksharing in linked models.
