Technical Sketching with an Introduction to CAD, Fourth Edition enables students to learn drafting concepts using the sketching methodology and apply them using CAD. This unique two-pronged approach is ideal because it reinforces learning in lectures and laboratory activities on CAD. Organized intuitively, it begins with chapters on sketching techniques and lettering; covers multiview projection, pictorials, auxiliary views, and sectioning; and includes chapters on dimensioning, tolerancing, fastening techniques and working drawings. This edition offers a revised chapter on 2D CAD, a new chapter on 3D CAD, and a continued examination of the link between technical sketching and computer-aided drafting.
