CAD  allows us to design products in a comfortable and effortless way. CAD is  used by engineers, architects, and construction managers to design the  desired output in 2D or 3D. The use of CAD engineers and architecture  enables the reconstruction of the design process. The advantage of CAD  is that it helps the engineer or architect finish their work to save  time. The benefit of this is that it decreases the errors since there is  a program that will aid you throughout your designing, since most of  the program does it for you. The limitation of CAD is that it does not  incorporate real life concepts, such as friction or gravity.

CAD revolutionized the design field for engineers by allowing them to  create correct, detailed designs quickly and efficiently, enabling more  efficient and cost-effective product development and new possibilities  for innovation. This allows for more efficient and cost-effective  product development and enables engineers to explore and confirm more  design alternatives. Overall, the use of CAD has greatly improved the  speed, accuracy, and efficiency of the design process, and has opened up  new possibilities for product innovation and development.
