When working on a Revit project, you can edit an element without checking out worksets using element borrowing. If another user has control over the workset or element, you make a request to borrow the element. You cannot edit it until the request has been granted and you have loaded the other user’s changes to it. For information about making and granting editing requests, see Borrowing ElementsRevit.
You can use Worksharing Monitor to track editing requests.
