Building Maker is a set of tools that draws a closer association between massing studies and building elements. It takes any overall building form described conceptually and maps it to real-world building elements (such as roofs, curtain walls, floors, and walls). Building Maker allows for a cumulative understanding of the relationship between expressive and built form as the design develops.
You can use Building Maker tools to create building elements from masses. See Creating Building Elements from Mass Instances.
