You can use massing studies to perform a variety of tasks. 
- Create in-place or family-based mass instances that are specific to individual design options. 
- Create mass families that represent the forms associated with often-used building volumes. 
- Vary materials, forms, and relations between masses that represent major components of a building or development using design options. 
- Abstractly represent phases of a project. 
- Study zoning compliance, both visually and numerically, by relating a proposed building mass to the zoning envelope and floor area ratio. 
- Assemble various complex masses from a library of predefined mass families. 
- Generate floors, roofs, curtain systems, and walls from mass instances with control over element category, type, and parameter values. Fully control regeneration of these elements when the mass changes.
