With advancements in the field of technology, several techniques can now be used to design engineering structures. Computer Aided Design is one such technique that makes engineering design convenient. In order to design and develop products used by end consumers, CAD engineering drawings prove useful. Right from the product conceptualization stage to final detailing, CAD is used extensively in engineering sector. Engineering CAD drawings are made with the help of AutoCAD software. This software makes complex engineering drawing simple and accurate. For architectural, electrical and mechanical CAD drawings, AutoCAD software is used. By this process, hand-drawn sketches can be converted into computerized blueprints quite easily. There is also the possibility of editing drawings, as these are saved in digital formats. Engineering CAD drawings can be modified if there is a change in the project. Further, these drawings can be saved in the hard disk of a computer and used for future references. Drawings can be mailed to the engineers working in any part of the globe.



In almost all engineering-based industries such as automotive, architecture, ship building, electronics, construction and aerospace, engineering drawings are used. For designing buildings, architects use CAD solutions. Civil engineers and architects are benefited by CAD while creating architectural, electrical, structural and interior designs. In mechanical engineering companies, CAD is used in a number of ways. It finds application in various manufacturing processes, right from creating engineering drawings to 3D modeling. Engineering companies are able to design products or components for machinery with the help of 3D modeling and pro-engineering packages. Engineering CAD drawings save money, time and ensure accuracy and precision. For things such as PCB designs and wiring layout designs, professionals of electrical and electronic engineering industries use CAD. Using engineering drawings, overall layout of the manufacturing unit can be designed. CAD has brought about a revolution in the engineering sector, as large projects can, now, be completed within the stipulated period of time. Quicker product turnaround time is enabled due to CAD engineering process, and, consequently, more and more products are introduced in the market.



Engineering CAD drawings are responsible for the advent of robotics into the manufacturing sector. For increased accuracy and production, more and more engineering processes are being automated. 3D geometry is used in CAD systems as input. The loading conditions are replicated by the system and information is provided if the structure can sustain the real loading condition. On the other hand, manual drawing does not have this attribute. In order to simulate real-time mechanism, 3D CAD geometry can be utilized. Hence, without generating a prototype, the functionality of a machine can be controlled. Further, on the FTP server file engineering drawings can be digitally stored. Once created, the documents can be accessed through the Internet easily. Engineering CAD drawing can be made private and other users can be restricted from accessing any kind of critical project information. Access level of each CAD document can be defined in order to provide administrative rights to limited users for accessing vital information. In order to complete manual drawings, drafters take many days. However, this not the case with CAD engineering drawings, which can be performed within a very short period, thus enabling progress in the projects.
