It is not enough now that the drawing be clear tothe man who makes it; it must be clear, ahsohitely clear, to theshop mechanic, who has no means of knowing the designers plansexcept through the information which the drawing gives on itsface. This requires that the di-aftsman should [uit himself in theworkmans place, and forestall, by the explicit nature of his draw-ing, all possible questions which may arise in the shop. In thisway only can he hope to avoid errors of construction and the con-tinual annoyance of endless explanation of his orders.
