From the time of hieroglyphic writing clown lo thai of modern graphic descripiion, man has known the need to represent his thoughts, discoveries, and inventions so that others may be informed. As our civilization becomes more complex, graphic representation, paralleling progress in science and engineering, likewise Incomes more complex. Moreover, as the history of graphics is studied, one important aspect stands out: the fact that only graphically may some kinds of information be conveyed or certain problems solved—for example, the impossibility of describing complicated mechanisms by other than graphic means is well known. To the engineer, therefore, graphics is a lifeline, connecting thought, invention, and research with the resulting actualities. To keep pace with advances in science and engineering, graphics in all its varied forms has been and is Iteing refined in many ways. In the past, graphic training has emphasized engineering drawing as a language of communication. The textbook "Engineering Drawing," by the authors of this volume, promotes the traditional conception and is currently being revised. Future revisions are contemplated as new procedures arc developed, as changes come forward in the training of engineers, and as new standards are adopted for industry...
