There needs to be a better to understand graphic for look up and look down. I don't care if revit reads my current view setting of there is a pull-down that changes it but the current graphic is messed up when it comes to understanding for these two completely different settings. Hoping users will get it is not funny. I would say to include a pull down that will switch between one or the other.
I would even say to have a live action section of MY building, with a view set up for that is the best method of understanding. When associated with associated level will of course dynamically change the character of the graphic in best case scenario.
