Cyclopedia of architecture, carpentry, and building : a general reference work ...
A ten-volume trade reference issued in 1907 by the American School of Correspondence in Chicago, compiled as correspondence-course instruction for carpenters, builders, and draftsmen. The plates are line drawings of orthographic projection problems: solids rotated on axes, dashed construction lines, dimension arrows, angle notations, and lettered reference points, useful as geometric line work, grid armatures, and technical diagram vocabulary.
