[Equest-users] Error: Exterior wall has negative net area

[glenn noronha]

Hi
I have created a two storey model. I created a separate shell for each floor as the floor area of each is not identical. Now certain areas on the first floor are open to below to the ground floor. While running the simulation the errors saying that certain exterior walls are having negative net area. On checking the wall location, it was found that all the areas which i had put as open to below are having these exterior walls.Please advice me on how to resolve this issue also want to know if my approach to a multi storey project by creating different shell areas was the right move.
Thank YouGlenn Noronha
