In a remodel project a window will be demolished in order to use the opening to allow HVAC ductwork an entrance to the building from a mechanical unit outside. I am wondering what would be BIM-smart way to demolish the window but to preserve the opening in the wall. With just a moment's thought, I came up with these options:
With either approach, I will have to fill in the rest of the wall so it surrounds the ductwork tightly. This is because, as I'm sure many of you would assume, the ductwork's cross-sectional area will be smaller than the existing window's.
Are there other options you have used which work well with phase settings and prevent otherwise-unnecessary splitting of the host wall? I'm glad to hear other approaches and thoughts on the two I listed above.

- Create a wall based opening family, place it to cut wall under existing phase
- Draw a curtain wall instead of a window to fill the opening, and set the curtain wall type to match the window, also under existing phase
- Demolish the curtain wall
I would maybe just cut the infill wall with an in-place void, which would be just about what Bradley is describing there... more or less exactly actually...
That seems straightforward, and has the benefit of accounting for the new wall which the contractor will build to match the existing wall. This new wall will have appropriate phase settings, too. Thanks for the suggestion!
