How can an architectural designer include walls from both the host model and a linked model in a wall schedule?

To include walls from both the host model and a linked model in a wall schedule, the option to select “Include Elements in Links” on the Fields tab is essential. This functionality allows Revit to recognize and pull in elements that exist in linked models, thus ensuring that walls from both the host model and linked model are integrated and displayed in the wall schedule.

When this option is enabled, Revit will effectively gather data from linked files alongside the primary project, allowing for a more cohesive view of all wall elements being utilized in the project. This is particularly useful for projects that require collaboration across multiple models, such as when different teams are responsible for separate building components.

While the other options concern sorting, formatting, or filtering aspects of the schedule, they don't directly address the inclusion of elements from linked models. Only by selecting the specific inclusion setting on the Fields tab can one ensure that linked model elements are accounted for in the wall schedule.
