Worksharing - Autodesk Revit Architecture 2015 Essentials - page 237

Now let's look at the Worksharing Display Settings available for worksharing
display in a project: Checkout Status, Owners, Model Updates, and Worksets.
These settings are based on the particular parameters in your project (number
of worksets, active users, and so forth). To activate any of these settings, click
the icon on the bottom of the view window (View Control Bar), and choose
one of the menu items from the list (Figure 10.18).
Figure 10.18 Worksharing Display Settings options
Activating any of the worksharing display modes from the menu toggles your
visibility settings and applies an orange border to the view you're in, alerting
you that you've activated the mode. To turn it back off, choose the Worksharing
Display Off option from the same menu.
Let's set some of these modes active one at a time and view the results.
Click the Worksharing Display button and choose Worksharing Display
Settings. Start with the Checkout Status tab; the checkout status helps you
distinguish between elements that are owned by you, others, or no one
(Figure 10.19).
