This volume comprises collection of notes originally intended to provide a basis for a course in elementary mechanical drawing. Designed for students on engineering courses, it provides a comprehensive foundation to mechanical drawing and is highly recommended for artists, engineers, architects, and others with a practical interest in technical drawing and drafting. Contents include: "Kinds of Letters in Common Use", "Lettering in Design", "Variations in Width, Height, etc.", "Suitability of Letters", "The Roman and Gothic Capitals and Small Letters and Numerals", "Off-hand Lettering", "The Old Roman and Roman-Gothic Letters", "Titles", "Bills of Materials", "Orthographic Projection", "Drawing as a Science", et cetera. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this book now in an affordable, high-quality, modern edition complete with a specially commissioned new introduction on technical drawing and drafting.
