Computer-aided design – definition and meaning

Computer-aided design Design-New-House Safety & Security

Computer-aided design or CAD refers to the use of computer software that supports the design process. The software helps us create, modify, analyze, and enhance a design. In other words, CAD is software that helps us design things.

Many people believe that computer-aided design refers just to drawings. In fact, it does not. CAD refers to any use of software to help in the design process.

CAD software replaces drafting by hand with an automated process. People working in architecture today have probably used 2-D or 3-D CAD programs. Those working in MEP or structural engineering have also probably used 2-D or 3-D CAD programs. MEP stands for mechanical, electrical and plumbing engineering

Computer-aided design multi-dimensional viewing

We can rotate the two- or three-dimensional diagrams. Therefore, we can view them from several different angles. In fact, we can see from the inside looking outward. Designers use a special plotter or printer for professional design renderings.

People use Industrial Computer-aided design for circuit design. The software may use system blocks to identify which components you need. It can also lay out the circuit diagram.

People like CAD programs because they can change different design ideas rapidly and easily.

After designing something, we can build and test it virtually. In other words, we can determine whether it will work. Companies like this because it reduces the cost of modifying prototypes and purchasing parts. Therefore, they get more mileage out of each dollar they spend.

A growing number of professions are using computer-aided design programs. Examples include artists, drafters, engineers, and architects.

The concept of designing geometric shapes for objects – computer-aided geometric design (CAGD) – is very similar to CAD.
