What is the purpose of the 'Reveal' tool in Revit?

The 'Reveal' tool in Revit is designed specifically to display building elements that are usually concealed in standard views, such as wall structures, framing, insulation, and other components that might be hidden behind finishes. This tool enhances the designer's ability to analyze and understand the underlying elements of the model without the distraction of the visible finishes. By using the 'Reveal' tool, users can toggle the visibility of these hidden features, making it easier to communicate design intentions and ensure accurate construction documentation.

In contrast, the other options do not align with the primary function of the 'Reveal' tool. Hiding elements for a clearer view pertains more to the visibility settings rather than revealing hidden components. Adjusting lighting effects is a separate function related to rendering and visibility settings, while editing visibility settings for views refers to the general management of what is shown or hidden in a view rather than explicitly revealing hidden elements. Therefore, the 'Reveal' tool serves a unique and critical role in providing a comprehensive understanding of a building's composition.
