When you create a new wall type, there’s a construction parameter called function. It has various options, like “Exterior” and “Foundation.” You might be wondering which one to pick – does it make a difference? What are the different wall functions for?
Wall function matters for filtering views and organizing wall schedules. You can set up a view to show only exterior walls, for example.
Some functions also affect the default instance values when you go to create a wall. For instance, a foundation will default to a base offset of -12 feet and a top constraint up to the level you are working on.
