Is there a way to cast shadows on a plan, where the full height of the walls and the roof are taken into account? Currently if I use a 3d view with a section box or take a normal floor plan the shadows are only cast from the objects to the top of the view range or the 3d section box. I am trying to see the extent of sunlight penetration into a internal space in plan view. Does anyone have a solution?

so have you gone to the 3D view and oriented it to the plan view you want and cast shadows there? to see it from the top with the roof and all, just orient to your site plan...

Perhaps you misunderstand. I want to see an internal floor plan with shadows(so I can see all of the internal fitout). But when I cast shadows they are only from the top of the walls in the view and do not include the roof. The result I want a shadowed floor plan as if I was standing inside the room on that day (so it takes into account the shadows from the roof as well

yeah, it doesn't work Not only is it really hard to place the camera to get an orthographic view, the shadows are still all over the place.

I think I know what youre talking about psymon, but Im pretty sure its a no-go in Revit. Shadows are only cast by objects that are visible, no workaround springs to mind. ie. if the ceiling/roof was visible to cast a shadow you wouldnt be able to see though it, so it would kinda defeat the purpose. To do what youre wanting, you'll need to do what eldados says and position a camera inside the room and play with its target to try and see the shadows cast by the windows and walls and stuff. Perhaps an alternative is to forget trying to view it in plan and try using high-angle 1 pt. perspective sections, or other combinations of section box + clever shadow angles. Hope this helps!

I have had a similar situation and solved it this way: 1) Open site plan with all view extents to unlimited and all categories that is needed ticked. 2) Turn on the shade. 3) Export this view as a jpeg or bitmap. 4) Import the image back into Revit and superimpose it on the plan view.
