I've tried and cannot see how to do it, nor have seen others mention it.
I want to create a walkthrough that doesn't look forward.
This would need to choose a focal point. I.e. the centre of the building and the view would be orbiting around the entire building.
This would be a very useful but very basic thing to do, but I'm sure either Revit makes it difficult to do when it should be easy, or not even possible at all, which would be disappointing.
