Hi there
I'd like to create some accurate shadow diagrams in plan view but I am having issues with Revit showing correct shadows on the terrain.
I have tried setting the shadows "Ground level at" multiple levels but it does not seem to work
Please see attached images. Both have the shadows set at the same ground level and same time of day.
The Perspective shows the shadows correctly but the plan does not. It ignores the topography completely and drops the shadows in the level down below.
Can anyone help? thanks in advance.
