We recently finished some retractable projection screen Revit families for Stewart Filmscreen, based in southern California. These are the kind of screens installed in the ceiling of a conference room or auditorium, where you might barely notice the screen is there until someone hits a button and it gracefully descends from a sleek minimalist enclosure. Since the screens are recessed products, the bulk of the work was in modeling all of the different canvas sizes and image areas available for each of the two models.
