Great question! The short answer is: it depends on what you're doing. When it comes to placing markups, the flow is one-directional — markups added during a Studio Session are pushed into the Revit model automatically. However, markup statuses can be updated from either side, making that part of the workflow fully bi-directional. So your Revit users aren't just passive recipients, they can actively manage and update markup status without leaving Revit.
