In this world where efficiency and accuracy are important all over the industry, Computer-Aided Design (CAD) has become a game-changer. A revolution in product design and development, computer-aided design (CAD) software has transformed a variety of fields, including architecture and automobile engineering. In this complete guide, we will understand “what is CAD Design”, why it is essential and what are the applications and uses of CAD.
What is CAD Design (Computer-Aided-Design)
Computer-Aided Design is also known as CAD Design in short. CAD design is a process of analyzing, creating, modifying, and optimizing designs for a variety of buildings and goods using computer software. CAD enables designers and engineers to work with digital models instead of traditional manual drawing techniques, which help in improving accuracy, productivity, and flexibility all the way through the design process.
CAD software creates comprehensive models of objects, structures, or mechanical parts by using exact geometric shapes, measurements, and limitations. To evaluate these digital models’ performance under various scenarios, they can be altered, viewed from multiple angles, and put through simulations.
Uses of CAD Design
CAD design is used in a wide range of sectors, all of which take use of its ability to drive innovation and accelerate workflows. Lets understand what are the CAD Design Software are used for:
Architecture and Construction
