Industrial drawing and geometry; an introduction to various branches of technical drawing
A 1911 technical drawing manual by Henry John Spooner, published in London and New York by Longmans, Green, for students of geometry and mechanical drafting. The plates are line diagrams: lettered construction figures with dotted projection lines, dimension arrows and angle marks, hatched sections, and axonometric boxes showing plan and elevation planes, all usable as ready-made geometric line art.
