Missing-View Problems. Using Layout A–2 or 3 or Layout A4–2 or 3 (adjusted), sketch or draw with instruments the givenviews, and add the missing view, as shown in Figs. 6.50 and 6.51. If dimensions are required, study §§11.1–11.25. Usemetric or decimal-inch dimensions as assigned by the instructor. Move dimensions to better locations where possible.In Probs. 1–5, all surfaces are normal surfaces.
