Which tool is used to create and modify 3D geometry in Revit?

The ‘Model’ tool is integral for creating and modifying 3D geometry in Revit. This tool enables users to construct a variety of modeled components, including walls, roofs, floors, and other elements, effectively shaping the building design in a three-dimensional space. The functionality provided by the ‘Model’ tool is foundational in building design, as it allows for precise manipulation and adjustments to the geometry being created.

In contrast, the other tools mentioned serve different purposes. The ‘3D View’ tool is focused on visualizing the model in three dimensions but does not directly create or modify geometry. The ‘Edit’ tool typically refers to functionalities for altering existing geometry rather than initially creating it. Lastly, the ‘Shapes’ tool does not exist in the same context within Revit and may be confused with other software or tools designed for graphical manipulation. Thus, the ‘Model’ tool is specifically designed for the task of 3D geometry creation and modification in Revit.
