To access room settings, which option must be clicked first?

To access room settings within the Cvent Diagramming tool, the first option that needs to be clicked is "File." This is because the "File" menu typically contains the underlying framework for managing events and configurations, where you can access various settings related to the event, including room configurations.

Navigating to "File" allows users to not only manage their diagrams but also access broader settings that impact the overall event layout. Upon clicking "File," users are generally presented with additional options that lead them toward specific settings, including room arrangements.

This logical structure of accessing features and settings through the "File" menu supports a more organized workflow, providing a clear path towards managing complex event layouts and ensuring the room settings are configured correctly.
