In which dialog does an architect select to include elements in links for a wall schedule?

The Fields tab in Revit is the correct choice for selecting elements to include in links for a wall schedule. This tab allows users to manage which data is displayed in the schedule by enabling the inclusion of fields that correspond to elements not only in the current model but also in linked models.

When working with wall schedules, architects can specify exactly which elements they want to include, giving them control over the information presented. This capability is crucial when dealing with linked files—such as different building models or phases—where ensuring that all relevant data is captured in a single cohesive document supports better project management and design coordination.

The other tabs, while important in their own right, serve other functions. The Sorting/Grouping tab is used to organize the information displayed in the schedule without directly selecting which elements to include. The Formatting tab adjusts the aesthetic presentation of the schedule but does not affect the element inclusion. Similarly, the Filter tab is designed to refine which items are shown based on specified criteria but does not allow for the selection of link elements for the schedule itself. Thus, the Fields tab stands out as the dedicated area for defining the specific content of schedules, particularly with respect to linked elements.
