INTRODUCTION ABOUT THE INDUSTRY
CAD SOFTWARE HISTORY
CAD software, also referred to as Computer Aided Design software and in the past as computer aided drafting software, refers to software programs that assist engineers and designers in a wide variety of industries to design and manufacture physical products ranging from buildings, bridges, roads, aircraft and automobiles, large aerospace and automotive companies, ships and cars to digital CAD CAM software ('CAM' is the acronym for Computer Aided Machining). Sketchpad was the world's first CAD software but the first commercial CAM software system, a Dr. Patrick J. Hanratty. For that reason it is Dr. Hanratty who is most often referred to as "the father First-generation CAD software systems were typically 2D drafting applications developed by a manufacturer's internal IT group (often collaborating with university researchers) and prim arily intended to automate repetitive drafting chores. The first CAD/CAM software tools emerged in the late 1950s and early 60s for use by automobile and airplane manufacturers with highly detailed McDonnell-Douglas (CADD released in 1966), Ford (PDGS released in 1967), Lockheed (CADAM AN INTRODUCTION TO THE CAD SOFTWARE INDUSTRY
CAD software, or computer-aided design software, is used to expedite the process of 2-D and 3-D design and drafting. CAD software can be used on projects as small as a single room in a house, such as a kitchen or bathroom, or as large as a municipal master plan. CAD software also lets engineers and manufacturers design components such as car parts or circuit boards; this process is referred to as CAM, or computer-aided manufacturing.
Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. CAD often involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD often must convey also symbolic information such...
