What feature is used to create a 3D representation of building mass during design?

The feature used to create a 3D representation of building mass during the design phase is Mass Objects. In Revit, Mass Objects allow designers to create and manipulate geometric forms that represent the overall shape and volume of a building without committing to specific architectural details. This helps architects evaluate scale, siting, and the relationship between different volumes early in the design process.

Mass Objects serve as an essential tool for conceptual design, enabling visualizations that can influence decisions regarding form, design alternatives, and spatial organization before detailed elements such as walls and windows are added. By utilizing these massing tools, architects can quickly adjust the geometry to meet design goals while assessing the impacts on factors like sunlight, shadows, and visual aesthetics.

The other features listed, such as View Range Control, Construction Documents, and Schedules, focus on different aspects of the design and documentation process and do not specifically facilitate the creation of 3D mass models for early design exploration.
