The conceptual design environment is a type of family editor in which you create conceptual designs using in-place and loadable mass family elements. When a conceptual design is ready, it can be loaded into the Revit project environment (RVT file). Creating designs in this environment can accelerate the design process. See Massing Studies.
To enter the conceptual design environment, use one of the following methods:
Use the Revit user interface and create new massing families that reside outside the project environment. If desired, you can load these massing families into a project.
Use the In-Place Mass tool in a Revit project to create or manipulate massing families. When accessed through the In-Place Mass tool, the conceptual design environment does not have 3D reference planes and 3D levels.
