It would be helpful, but I feel that most of the users (especially Architects) have pretty strong preference on how things are presented in floorplan. Some countries might have fixed way of presenting certain things. That means, users should be able have their own 2D symbols for the assets or a way to modify the existing ones to their liking.
In Revit linkin assets to Revit families kind of work, but it's such a hassle to get their locations to match (editing of family origins is usually required) that we only use it very rarely.
