Which option is not a feature found under the Revit application menu?

The Properties Panel is not considered a feature found under the Revit application menu; rather, it is part of the user interface found in the main working area of Revit. The application menu primarily includes options related to the management of the Revit files, such as creating new projects, opening recent files, and saving projects in various formats.

The New Project option allows users to start a new design, facilitating the initial setup of a project file in Revit. Open Recent lists recently accessed files, providing easy access for the user to revisit previous work. Save As enables users to save their current work under a different name or format, ensuring that various iterations of a project can be preserved. The Properties Panel, however, provides specific properties and settings for selected elements and does not reside within the application menu, distinguishing it from the other choices.
