Orientation (Plan) of 3D view from top

I am setting up some 3D views from top (camera, non perspective) for illuminance studies.  The orientation of my floor plans is such that landscape sheets capture it, ie, plan east-west is the horizontal (long) axis.  When I set up my camera view to the top it ends up rotated to portrait (90 degrees clockwise in fact).  True north is exactly 45degrees between these two (the building sits at a 45 degree angle).  I cannot find any way to rotate this view (apart from rotating the crop region, which I try not to do based on past experience).  I am using Revit 2016 . . . does anyone have any ideas on how the orientation of 3d views can be set?  I've tried manipulating the compass around the view cube with some success, but it doesn't snap to rotation points so it ends up a bit off (rotated a degree or two off of parallel to a sheet side).

Doh! It never fails, just posting a question can ensure that the next thing I think of works.  Right click on the compass has a menu item to orient to a view.  Pick my overall plan and  voila, it is set up correctly.

Yes you can align a 3D view to any given View or any named Reference plane in your project.  How to get to it is a bit obscured behind the cube context menu.  It would be easier for users if they include the option in the View properties palette.

Why do you need a camera? Can you use the 3D View icon then choose Top from the Cube? The 3D top view would based on Project North.

Well it turns out that this won't work for what I want to do.  I need a non perspective camera view to look at the effects of daylight through the windows while keeping the effect of the roof and overhangs.  The normal floor plan views will render as if there is no roof/ ceiling.  If I reorient my view with the cube context menu (as noted above by two of us) this has the effect of making the camera view now render like an ordinary floor plan.  One big clue to this was the eye and target elevations: initially for my lighting view I set the camera height as 7' and the target height as 0'.  When I rotate or reorient the view it resets the camera height to hundreds of feet and the target height to 20 something feet.  (above all of my roof heights anyway), but it still shows the floorplan.  So now the roofs and ceilings are turned off, it is as if now there is a cut plane.  My only way of having this view orient correctly is to rotate the crop window (opposite rotation trick here).

Uncheck Section box for that 3d view.

That works to a degree. But when I reset the eye and target elevations (to 7' and 0') the view reorients to the incorrect orientation again.  This might be something specific to a camera view without perspective, because normal 3D views behave correctly (but don't let me do the illuminance renderings correctly).

It works with 3D camera views.  You just need to lock orientation of the view before changing the eye and target elevations.

Sweet!  Thanks for your time and patience.  I had never even noticed that little icon to lock the orientation at the bottom . . . just that the checkbox was greyed out.
