color:#1F497D'>In a project in which a new construction building is being built
into the side of a hill, I encounter several spaces that will require both Exterior
Wall Construction and Underground Wall Construction. I am curious how it will
effect the building simulation if an exterior and underground wall were both
modeled on the same vertex point of a space. Is this recognized?
Does this result in accurate simulation? Should I just create an extra
vertex point to make one half be exterior and the other half underground?<o:p></o:p></span></p>
