Figure 3 shows the guidelines to use for internal and external radii. Figure 8 illustrates the recommended rib design guidelines. The design of a rib should be derived from the structural, flow, and assembly requirements of the part.2 FIGURE 5 - Proper contour design FIGURE 6 - Drafting guidelines for nominal wall thickness FIGURE 7 - Wall thickness changes due to rib placement FIGURE 8 - Rib design guidelines ESCR Design Guide 3 BOSSES A boss, demonstrated in Figure 9, is a protruding feature that allows for fastening components.
