When modelling a new project begin with Ceilings.
Select the “Roof Tool” and pick the “Actually Ceiling” Favourite.
Model the Ceilings at the correct Elevation and Pitch.
Note: Make sure to model the Ceilings to the outside of the Exterior Walls, to ensure accuracy when it comes to Thermal Calculations.
Note: Remember to differentiate and separate Ceilings over Conditioned and Unconditioned Typologies.
