Shade and Shadow on a Narrow Site

these sun studies were actually quite hard fought.
Here's what doesn't work:
importing the Rhino files into revit... they are all some bizarre polysurface that very much does not like to interact with anything or anyone


Measuring sun angles in rhino with a spotlight... (this would actually work if I got the spot far enough away and big enough... like however far away and big the sun is...)


What does work: (and this will save someone out there two-four hours of their life)
Just draw the walls at the accurate height around the plan (this is in Revit), use advanced model graphics (a little white curved plane button at the bottom of the screen) and within that dialog you can change latitude and longitude, time, etc.

now here is the important part:

do not do it in plan view


do the advanced graphics in your site plan view...


otherwise you will waste a fair amount of time trying to figure out why the shadows all go the same distance regardless of wall height... i would imagine
