How to create an elevation of a neighbor to examine a proposals shadow impact?

How to create an elevation of a neighbor to examine a proposals shadow impact?

I've tried various elevation methods, sectional perspectives, transparency and other materials settings. It seems that Revit requires visible objects to cast shadows with. Is there a workaround?

Create the neighboring building using mass forms?

I don't understand your question about my question.

 

Assume the neighbors/context are drawn as a mass. I wish to set up elevations of the neighboring/context masses to examine the shadows cast by the proposal on the subject site.

Hi

Create a Roof using Google Map or survey if available as a base..

and walls using Eave offset to the Roof Plan profile..

 

Cheers.

I don't understand this response.

I know how to model. I wish to examine the shadows cast on to a model.

Hello

Create Elevation or 3d view for each side for shadow analysis.

set the location, date and time to examine the shadow..

sample..

Hi Ganesh. Thanks for all your effort.

In your model, how can I capture the shadows from proposed blue object without having the blue object visible in the scene?

Are you looking for something like this.. you can achive this in any view i guess..Are you looking for something like this.. you can achive this in any view i guess..

 

VG- model - surface all white solid and edges ( projection lines ) also white.. and switch on the shaodw.. thats it..VG- model - surface all white solid and edges ( projection lines ) also white.. and switch on the shaodw.. thats it..

Hello and thanks again Ganesh.

The shadow I need to see is behind your left hand foreground tower. How do you show the shadow beyond the tower?

Hello

 

Use Camera angle / Elevation which captures the required shadow.

else you may make the view transparent ( VG, model transparent ) 

and create a manually filled region.

 

You may need to add two views overlapped or bit of manual work to achieve what you are looking for.

cause the moment you hide a 3d object, the shadow will vanish..

and if you want to keep the 3d object, its gonna interfere with the shadow visibility.

 

best luck

Thanks Corsten,

 

In summary, it can't be done?

It seems like a very simple task/ask.

Surely someone in Revit land has cracked this conundrum.

Then why can't you figure it out? Maybe, because invisible objects don't cast shadows?

Drafting is a breeze and Revit doesn't always work the way you think it should.

In my view its a weakness of Revit that you can't use this to do a shadow study.  Shadows can't show from behind or above the cut plane, so you cannot see how the shadows project onto surfaces.

Absurd.

It's now 2024. I've installed 2025. And I'm walking down the identical path. Trying to create an elevation with shadows cast on a neighbour. I can't find a way.

 

In plan, the simple solution is setup a camera and turn off perspective/turn on orthogonal view. This works perfectly.

 

In elevation, setting the direction and cut line doesn't seem to work.

 

Any tips appreciated.
