When working on a team project that is enabled for worksharing, other users may request access to elements that you are working on. Use this procedure to explicitly grant these requests.
There is also an implicit granting process that occurs when you Synchronize with Central and relinquish the requested elements.
Hover your cursor over the dialog to highlight the requested elements in the drawing area. Click Show to maintain the highlighting.
Go to step 6 if you responded through the notification dialog.
You can expand the request to see the element name. To view the element, select it from the list and, if the element is not visible in the current view, click Show.
If you try to grant a request that has an asterisk (modified element) next to it, Revit notifies you that you have not synchronized your changes with central. You must either synchronize your changes with central and then grant the request, or you must relinquish your elements without synchronizing with central. For more information, see Relinquish Ownership without Synchronize with Central.
If you try to grant a request that has a caret (deleted element) next to it, Revit will ignore the request because the element is no longer available for editing.
