CAD is the acronym for computer-aided design and is also known as computer-aided drafting and design, or CAD. CAD systems are the combination of software or programs and hardware equipments that enables people, especially engineers and architects, to use computer technology for the process of drafting and design of everything from simple machines to skyscrapers.
CAD systems enables the user to work with their design in a virtual environment, providing it by use of input tools such as a digitizing tablet, a mouse, keyboard and outputs it in the form of electronic data for printing of machining operations using high-quality graphics monitors or a special printer or plotter. Computer-aided design system are developed according to the processes it is define to perform.
Graphic-based CAD software employs a raster-based or in other words, pixel environment, while industry-based software typically utilizes vector-based or linear environments. The latter are usually for constructions, manufacturing works and other industry related designing work.
CAD systems allow users to easily view their designs from any specific angles and view it in any desirable scale, making the drafting or design process a much more easier job to do. There are many functionality available in different computer-aided design system depending upon the type of drafting or designing work that needs to be done. Editing designs are even possible and very simple to do. Errors or mistakes can easily be corrected and the computer can keep track of the values inputted to a design and automatically changes it accordingly when the user alters a value.
There are many different computer-aided design programs available on the market today and you can simply buy CAD software that could be installed and runs on your personal or office computers. Several decades earlier, computer-aided design applications were only available for use on specially designed computer and are quite expensive.
CAD systems are nowadays integrated into learning systems and schools, especially colleges and universities offer courses to their students on various computer-aided design applications. This is to equip students with the knowledge on how to use computer-aided design programs and increase their chance of landing on jobs. Students in the field of engineering, architecture and other related courses usually have these CAD related subjects as part of their course.
Computer-aided design certainly plays an active role in the development and advancement of a society whether by means of infrastructure building, vehicle designing or graphics design. Many professionals are now using CAD programs in their field for ease of work and better productivity. Candidates that have knowledge in using computer-aided design software are always in demand by hiring companies.
