Rudiments of the art of building : in five sections : general principles of construction, materials used in building, strength of materials, use of materials, working drawings, specifications and estimates
Edward Dobson's 1871 London manual of building, published by Lockwood & Co. and aimed at students and practising builders, sets out general construction principles, materials, strength, and working drawings. The pictures are plain line engravings of timber centering under an arch, a wooden bracket with curved brace, a sloping truss joint, and a sectioned block with rods. A designer could take from them the clean hatching and diagrammatic line style used to show structure and internal framing.
