Computer aided design (CAD) uses computer technology to create detailed, dimensional models. In many engineering environments, it's either used in conjunction with manual drafting techniques or has replaced manual drafting completely, with all design work performed on computers rather than with traditional tools. Below, learn more about how CAD has revolutionized engineering.

How Do CAD & CAM Differ?

CAD and CAM, or computer aided manufacturing, are both parts of the design process. But CAD focuses on using computers to design drawings and models, while CAM uses computers to control the tools utilized during manufacturing. CAD is concerned primarily with the creation of a design, and CAM helps bring the design to fruition by controlling the machinery that produces it. For instance, a CAD model might be fed into a CAM-assisted machine to create a manufactured product.

How Is CAD Used in Engineering?

In engineering, CAD is used to make 2D drawings and 3D models. Designing drawings and models with this amount of dimension and detail is nearly impossible with traditional pencil and paper, so CAD has allowed engineers, architects, designers, contractors, and other professionals the opportunity to more accurately visualize the construction and the end result. CAD also lets users modify, analyze, or optimize the model as necessary to ensure it meets the project goals.

Why Is CAD Software So Innovative?

CAD simplifies, streamlines, and speeds up the drafting process and results in more accurate representations. These representations can be changed as needed to quickly and easily improve the quality of the design. What may have previously taken weeks of work by teams of engineers can now be accomplished by one person in a matter of hours or days. 

Visually accurate renderings keep everyone working on the project on the same page. There is less guesswork and less room for error when everyone has the same views and the same perspectives on the project. These renderings also keep work in-house, averting a firm's need to outsource their drawings and models to specialized businesses, which saves money and lets the firm offer a more one-stop-shop experience.
