Revit already has a Stacked Wall family, but in our Construction market- Viet Nam- that does not enough for us to create and manage the Model. Because we use the Revit model for Quantification, for creating Shop Drawing... and we need to separate the Wall to Masonry Wall and Finish Wall. With the Finish wall, we can add Room information (Room Name, Room Number) to manage or Quantification. I think you can create another Wall Family- STACKED WALL HORIZONTAL- Masonry Wall in the center and 2 Type Finish Wall on 2 sides. That will reduce a lot of time modeling, after modeling this Stacked Wall horizontal, we can break it up into Basic walls for the next work package
