The Worksharing Monitor for Revit 2012 facilitates the use of Revit software in a file-based worksharing environment, in which multiple people work on one project. For workshared projects, the Worksharing Monitor answers questions like the following:
The Worksharing Monitor works with all Revit products, including Revit Architecture, Revit MEP, and Revit Structure. If you are working on one or more workshared Revit projects, install the Worksharing Monitor on your computer. When you open a workshared project in the Revit software, also start the Worksharing Monitor. (Using the Worksharing Monitor with worksharing projects is not required, but it is strongly recommended.)
For information about setting up, using, and managing workshared projects, as well as terminology and concepts related to worksharing, see Working in a Team in the Revit Help.
