CHAPTER 13 Modeling Floors, Ceilings, and Roofs

Floors, ceilings, and roofs, which may seem like simple building components, can sometimes prove to be difficult to model and detail in your project designs. In the previous chapter, you learned about creating and customizing walls. Many of the objects in this chapter depend on walls and curtain walls to define their boundaries, but both groups of object types are system families that use a built-up set of layers that are applied to a sketched form. Whereas walls mostly rely on a linear path, floors, ceilings, and roofs rely on a boundary sketch.

In this chapter, you’ll learn to:

  • Understand floor modeling methods
  • Model various floor finishes
  • Create ceilings
  • Understand roof modeling methods
  • Work with advanced shape editing for floors and roofs

Understanding Floor Types


Floors are likely to be one of the first sketch-based elements you will encounter in Autodesk® Revit® software. Some families in the default libraries are floor hosted, so you must first have a floor before you’ll be able to place such components. Consequently, floor-hosted components will be deleted if the floor that hosts them is deleted. You can find a more detailed discussion on creating families in Chapter 14, “Designing with the Family Editor,” but for now let’s review the fundamental types of floors that can exist in a project: a floor, a structural floor, ...
