Adding Shading & Obstructions for multi level dwellings

 

As a general statement, the obstruction heights can be considered as "how high above the floor on level 1 (of the dwelling or unit) 
This does also mean that if you are doing multiple units in a large building, as the height above ground changes you also need to update the shading height to ensure the correct shading is modelled.

 

To demonstrate this, please see the attached document to aid in determining height of shading and obstructions.
