Book excerpt: CAD/CAE Descriptive Geometry provides a sound foundation in the fundamentals of plane geometry (mathematics), orthographic projection (technical drawing), and high-speed communication methods (digital computing). The material presented in this textbook is based on the premise that readers have access to IBM PC or PS/2 compatible workstations running AutoDesk software. The chapters cover the basic geometry topic in detail using the CAD workstation. The book is an excellent industry and institutional reference, as well as a student text.
