Sometimes you can look at something for, literally, years without seeing the obvious. While using a 3D DWF (during a phone conversation) I gazed at the List, Thumbnail, Markups and Model panel and wondered, why doesn’t Revit have this?
Why does a Building Information Model application only offer a document’centric representation of its model? The project browser is configurable, but only for view/sheet related items.
I can see plenty of uses for the sort of model tree seen in Autodesk Design Review when you export a 3D DWF from Revit (or AutoCAD Architecture for that matter). One place a hierarchy would help is understanding nested family structures (in both project and family editors). Facilities Managers would love a configurable model browser that showed floor and room based views of model assets. I know it would be handy in retail.
Maybe it’s because Revit BIMs are still regarded, wrongly, by many as document creation tools?
