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�, 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� programming to solve a specific spatial problem. In addition, Autodesk Inventor� 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.
