Which tool is used to create a key schedule?

The tool used to create a key schedule in Revit is called a Key Schedule. A key schedule allows users to define a schedule that can reference multiple instances of a certain element type, such as doors or windows, and can be particularly useful for managing a selection of items that share common properties.

In Revit, when you choose to create a key schedule, it provides an organized way to manage these elements using a specific set of keys that can be referenced throughout the project, which enhances consistency and efficiency. This type of schedule allows for easy updates and improvements across the project by changing a single entry in the key schedule rather than adjusting each individual instance.

The other options, while related to scheduling or organizing data within Revit, do not specifically pertain to the creation of key schedules. The Schedule/Quantities tool is broader and is used for various types of schedules that account for quantities of elements but does not specialize in key scheduling. Note Block serves a different purpose, primarily for annotating notes and instructions within a drawing, while Material Takeoff focuses on detailed quantity information related to materials used in the project rather than organizing elements through keys.
