A textbook for three categories of students: those with drafting skills who need to apply it to electronics; those with electronics skills to need an introduction to drafting principles; and those who need expose to both areas. Includes three glossaries, including computer-era definitions of familiar terms. For the third edition, the chapters have been rearranged to keep similar materials together, so instructors can easily tailor a specialized one-term course, or use different sections to offer up to three courses. First published in 1983 by Merrill and again in 1993 by Macmillan. Annotation copyrighted by Book News, Inc., Portland, OR
