Book excerpt: Excerpt from A Manual of Engineering Drawing for Students and Draftsmen There is a wide diversity of method in the teaching of engineer ing drawing, and perhaps less uniformity in the courses in differ ent schools than would be found in most subjects taught in tech nical schools and colleges. In some well-known instances the attempt is made to teach the subject by giving a series of plates to be copied by the student. Some give all the time to laboratory work, others depend principally upon recitations and home work. Some begin immediately on the theory of descriptive geometry, working in all the angles, others discard theory and commence with a course in machine detailing. Some advocate the extensive use 'oi models, some condemn their use entirely. Different courses have been designed for different purposes, and criticism is not intended, but it would seem that better unity of method might result if there were a better recognition of the conception that drawing is a real language, to be studied and taught in the same way as any other language. With this conception it may be seen that except for the practice in the handling and use of instruments, and for showing certain stand ards of execution, copying drawings does little more in the study as an art of expression of thought than copying paragraphs from a foreign book would do in beginning the study of a foreign language. And it would appear equally true that good pedagogy would not advise taking up composition in a new language before the simple structure of the sentence is understood and appreciated; that is, working drawings would not be considered until after the theory of projection has been explained. After a knowledge of the technic of expression, the penman Ship and orthography, the whole energy should be directed toward training in constructive imagination, the perceptive ability which enables one to think in three dimensions, to visual ize quickly and accurately, to build up a clear mental image, a requirement absolutely necessary for the designer who is to represent his thoughts on paper. That this may be accomplished more readily by taking up solids before points and lines has been demonstrated beyond dispute.
