Not even the result in dynamo is correct if the wall is not attached. What is the units of this? or is it just difference because how Revit calculate the wall?
Hi @Simon_Fiele1
I saw a definition in the topic you’re refering to, where the actual area taken is the area of the intersection of a wall and a room. This area is usually smaller than the area of the wall itself.
From the list you have I think you’ve used something similar and that might be the problem.
this chunk is not not calculated by the definition, but is still a part of the wall area
