Flatness and cylindricity both involve areas (2-D), but the area for cylindricity wraps around a surface. As seen in Figure 4, a cylindricity tolerance defines a tolerance zone consisting of two concentric cylinders. Cylindricity tolerance is used for cylinders only, and really controls taper, roundness, and straightness.
