What action will not successfully open a project in Revit?

The action that will not successfully open a project in Revit is pressing Control-N on the keyboard. This keyboard shortcut is designated for creating a new project, not opening an existing one. Therefore, using this command does not provide access to an existing Revit project file.

In Revit, you can use various methods to open existing projects, such as selecting "Open Project" from the application menu, dragging a project file into the Revit interface, or utilizing the "Open Recent" option to quickly access recently used files. These methods are specifically designed to facilitate opening existing projects within the software, whereas the Control-N command serves an entirely different purpose.
