What view must be active before exporting a schedule?

For exporting a schedule in Revit, the schedule view being exported must be the active view. This is essential because the export function is designed to work directly with the data displayed in the currently active view. When you select the export option, Revit uses the specific information from that view to generate the output file, whether it's in a format like Excel or a PDF.

Activating the schedule view ensures that all the customizations and specific filter settings you've applied to that schedule are honored in the export process. Other types of views, such as sheets or floor plans, do not contain the necessary data to export the schedule correctly. The functionality is purposefully designed to streamline the workflow, making it straightforward to export exactly what is visible in the active schedule view.
