Final answer:
The box to the right of the Revit 3D window is called the ViewCube, which is a tool for orienting and navigating 3D models efficiently.
Step-by-step explanation:
The 3D box to the right of the Revit 3D window is known as the ViewCube. The ViewCube is an interactive tool that allows users to rotate and orient the 3D model in space. It offers a quick and intuitive way to change the viewpoint by clicking on the various faces, edges, and corners of the cube. For example, clicking on the top face of the ViewCube will give you a plan view (looking straight down), while clicking on a corner can provide an isometric or perspective view of the model.
It is used to show the sequence or progression of events over time. In this case, the timeline represents the history of the 3D models in the Revit project, with the 'Big Bang' representing the starting point and the 'Present' representing the current state.
