Computer-aided design (CAD) is a process for digitally creating two-dimensional drawings and three-dimensional models of real products — even before they are created. With 3D CAD, you can quickly share, review, simulate, and change designs, which enables you to quickly develop novel and distinctive products. Dr. Samuel Geisberg founded Parametric Technology Corporation (PTC) in 1985 with the aim of defining a fundamentally new approach to CAD software. This breakthrough resulted in the first parametric and feature-based CAD software for solid modeling on the market, now known as Creo, which represents the industry standard for product design and development software. After more than three decades, the product development sector is now beginning to embrace the next wave of technology-driven innovation, as many other industries have already done. Using system blocks, the program can determine which components you need. In addition, the program can design the circuit diagram. People like CAD systems because they allow them to quickly and easily switch between different design concepts. After we design something, we can digitally construct and test it. In other words, we can verify that it works. Companies appreciate this because it allows them to minimize the costs of producing prototypes and procuring components. Computer-aided design systems are being used by more and more professional groups. Computer-aided geometric design (CAGD) is a technique for creating geometric shapes for objects that is very similar to CAD.
