A 3D view in Revit is a way to see and interact with a building model in three dimensions. It allows you to visualize how the different building elements fit together and how they relate to each other. With a 3D view, you can see the building from any angle, zoom in and out, and rotate the view to get a better understanding of the design.

Revit 3D modeling refers to the process of creating three-dimensional representations of building elements within the Revit environment. Using Revit for 3D Modeling: Revit provides a robust set of tools for creating 3D models of buildings and their components.
