This book uses the latest technology to address the basic theories involved in solving descriptive geometry problems. By incorporating the practical use of computer-aided drafting and design software into the theories and solutions, Descriptive Geometry: An Integrated Approach Using AutoCAD(r), 2E gives readers an edge that traditional descriptive geometry textbooks don't provide. Structured to be compatible with various releases of AutoCAD, it is ideal for anyone entering the work force. A section has been added to the end of each chapter in this book that covers the use of AutoLISP(r) programming to solve a specific spatial problem. In addition, Autodesk Inventor(r) has been incorporated into the solution of advanced problem-solving, as well as flat pattern development (sheet metal). This unique integration of current technology, plus fundamental instruction in descriptive geometry principles make this a valuable addition to every successful design-oriented architectural and engineering education and training program.
