The Peculiarities of Computer-aided Engineering and Design

AutoCAD - Complete Tutorial for Beginners 

In conjunction with the use of automation systems for engineering calculations and CAE analysis, computer-aided design (CAD) systems are usually used at this time. Information from CAD systems comes to CAM (Computer-aided manufacturing). First of all, design automation is a synthetic discipline, as it includes various modern information technologies. For example, CAD technical support is based on the operation of computer networks and telecommunication technologies, and CAD practices the use of personal computers and workstations. Speaking about the CAD software, it should be noted the variety of methods used: computational mathematics, mathematical programming, statistics, discrete mathematics, artificial intelligence. CAD software systems can be compared with one of the most complex modern software systems, which are based on such operating systems as Windows, Unix, and such programming languages as C, C ++ and Java, as well as modern CASE-technologies. Almost every design engineer should have knowledge of the basics of design automation and be able to work with CAD tools. Since all design departments, offices and design bureaus are equipped with computers, the designer’s work with such a tool as a regular Kuhlmann or calculations using the slide rule became irrelevant. Consequently, enterprises operating without CAD or using it to a small extent become uncompetitive, since they spend much more time and financial resources on design.
