Which tab in Revit would you find tools for modifying existing elements?

The Modify Tab in Revit is specifically designed for altering existing elements within a project. This tab contains a variety of tools that allow users to perform actions such as moving, rotating, mirroring, scaling, and modifying the properties of elements already placed in the model. It serves as a central hub for editing tasks, facilitating quick adjustments to the design without the need to access other tabs that might cater to more specialized functions or creation tasks.

In contrast, the Architectural Tab focuses primarily on tools for creating new architectural elements, such as walls, doors, and windows, rather than modifying them. The Analyze Tab is geared towards performance analysis and does not offer modification tools for existing elements. Lastly, the View Tab contains tools related to how the model is presented visually, such as creating views and setting visibility settings, but does not include utilities for modifying elements. Thus, the Modify Tab is the most relevant and appropriate choice for modifying existing elements within Revit.
