A space may contain a void or any sub surface. how do we easily get the netArea and gross Area of the space with a void or sub surface. The void is on the roof ceiling of a space.
Since you allready asked about NetArea and Gross Area and got a full answer from Julien, I will asume your are looking for the Volume of the space.
You can find all the relevant methods for space object in the SDK docs.
To answer what I think you asked: the void in the roof has no impact on the volume calculation nor on the floor area calculation. To prove it I created the following space:
Calculating its Volume and floor area using space.volume and space.floorArea yield the same outcome when the void was present, without void and with skylight window.

Can you specify what software you are using. Also are you looking for floor area, or net/gross area of surface with sub-surfaces?
