7-13 Rounded Shapes—Internal
Internal rounded shapes are called slots. Figure 7-57 shows three different methods for dimensioning slots. The end radii are indicated by the note R-2 PLACES, but no numerical value is given. The width of the slot is dimensioned, and it is assumed that the radius of the rounded ends is exactly half of the stated width.
