This is how I do it:

  • Create a new 3D View.
  • Hit F8 to bring up the dialogue box
  • Click on the carrot on the rightmost side of the dialogue box
  • Find the (floorplan) view you want under the Orient to View drop-down
  • Turn on your shadows and it will show like there is a ceiling/roof

I hope this helps.

Hi BM3975,

we also have to show a similar shadow study for Town planning. We have tried many, many ways of doing what you requested, but haven't found an answer.

The main issue is:

if you cast shadows in a normal orthographic plan it "culls" anything above the view cut line. Not only does this mean that light leaks through the ceiling, it also means that (for example) the 10 storey building adjacent will not cast a 10 storey shadow, just one that is the height of the cut line.

Things you can try (personally I haven't got them to work, but you might:

(1) Try using a othrographic camera view (place a camera and uncheck the perspective box on the menu bar) to create aview from jsut below your ceiling line looking straight down.

(2) In a site plan view (from say 10m above your roof) try using the plan region tool to cut out the section of floor plan you require.

Utimately I have had trouble with even using hidden line shadows on elevations (I have a thread about it somewhere, whcih no-one has replied to).

In the end I have had to do axonometric 3d views of the external building.

so.... I don't think there is an answer... sorry

The funny thing is when I do this I get wierd artifacts - see attached image - anyone else get these?

It looks to me as if it is still not taking into consideration the roof/ceiling above. Judging by the amount of light in the rooms, it is showing light flooding into the room over the walls. For example, looking at the top most plan, the light is coming from the top left of the view so the only light in the rooms to the bottom of the plan should be from any window openings or door opening into that room.

...Interesting...

Did the view, when oriented to floor plan, default to a aerial or site plan view or was it actually under the roof in the plan view? The problem I have been running into is when I do an orient to floor plan, it defaults to the aerial or site plan view, and as soon as I try to eye or lower the target levels, things start getting very distorted. And of course I can't hide the roof.

...I'll have to try this method myself when I get back into the office...

Try setting the cut plane of the plan view above the floor/roof above, then make the floor/roof transparent.  I tried it and the floor appears to still cast a shadow, so only the windows let in the light.  Please let me know if you have success with it.

Hey thanks, I ended up turning my roofs. and just accepting there will be light inside at some points where I don't need it.  It didn't effect the area I was studying.

Hi, all--I have a similar problem.  I'm trying to do a solar analysis in plan of a pavilion open on three sides.  I'd like to see the shadows cast by the walls and roof of the pavilion in plan, but when I do a solar analysis on Floor Plan Level 1 or in 3D View with a section box, the model only casts shadows for the visible portion of the pavilion cut at about 4'.  Has anyone discovered a way of casting shadows for an entire structure but with only of the portion of the structure visible?

 

Thanks!

Hi Guys,

Im having the same problem but I may have a solution:

1. Go to 3D view

2. In the properties panel on the left, click section box

3. Position the arrows of the section box so that the top is cutting through the roof of the house. 

4. Then do solar study.

See if this works. If not, maybe you could try doing the section box so that it has not gone through all the ceiling but through some if it. Then just hide the ceiling and you should just get windows and openings where the sun penetrates

Here is the solutionSmile

Make a camera view, VIEW TAB, 3DView, Camera. Before placing the camera untick the Perspective box.

In the properties you set the height of your Eye and target. Eye level should be below ceiling of the plan you want to study. Target could be 0. In the view cube of the camera, go to TOP. Now you have a perfect Planview and when you run your solarstudy now, Revit still recognices that there is a roof and in general elements above the view. 

Like this you get a realistic view of where directs sun/shadow will be during the day and year.
