Mechanical drawing problems
A 1917 McGraw-Hill drafting exercise book by Charles William Weick, made for American engineering and trade-school students learning orthographic projection. The plates are line-only drafting sheets: plan, elevation and auxiliary views with dashed hidden lines, center lines, arc constructions, arrowed dimension strings and fractional figures, plus hand-lettered labels — useful as technical-diagram texture, measured-drawing motifs and lettering reference.
