Which tool allows you to create a single opening that cuts through multiple floors, ceilings, and roofs?

The correct choice, Shaft Opening, is specifically designed in Revit to create an opening that extends vertically through multiple elements, such as floors, ceilings, and roofs. This tool is particularly useful for applications like stairwells, elevator shafts, and ductwork, where a continuous opening is required across several levels of a building.

When you select the Shaft Opening tool, it allows you to define the vertical cut through an entire structure, making it appropriate for scenarios where a singular, uninterrupted opening is necessary. This capability ensures that the opening is accurately integrated across all layers of building elements within its path, streamlining the design process and maintaining the integrity of the overall architectural model.

Other tools, such as Opening by Face and Wall Opening, serve more localized functions. Opening by Face is meant for creating openings within individual wall elements but does not extend through multiple levels or categories of elements like the Shaft Opening does. A Wall Opening is limited to cutting through a single wall rather than a span involving multiple floors or ceilings. Vertical Opening is not a standard tool in Revit terminology and might cause confusion since it does not represent the specific functionality required in this scenario. Overall, the Shaft Opening stands out as the most fitting tool for creating a comprehensive, multi-level opening.
