Computer-aided design, also called CAD, encompasses a vast variety of computer-based tools. They are made to aid engineers, architects and design professionals in their tasks. Every step of designing using CAD requires the use of software, and sometimes developed hardware. Modern systems such as 3D modeling, 2D drafting and solid design modelers use CAD as their primary system. The manufacturers use CAD for the design of virtual products that can be tested and evaluated to determine the performance. Without CAD everything involved with making a product, and later testing it would cost a lot. CAD is a groundbreaking design tool, that can be used to create cost-effective solutions and efficiency-enhancing processes.
cad is used to create and design products. They are used as products by customers. It is the most widely used tool in the development and design of machines. It is also widely used in the design of every kind of building. Industries in the engineering sector use CAD beginning with the conceptualization of the product throughout the entire manufacturing process.
CAD is utilized by a lot of industries of today. Engineering, architecture, construction and construction, mechanical aviation, ship building electronic, electrical or automotive, mention it, and the business will utilize CAD for one design or other purpose. It is no wonder that there is such a high demand of CAD as an engineering tool.
3D modeling and surface construction techniques began to be employed in the early 1960s, specifically in the automotive and aircraft industries. In the beginning, there was the invention of the sketchpad that can be described as an early precursor to CAD. The aerospace industry began to utilize CAD commercially and was the first to promote the use for CAD as a design tool.
With the growing use of computers, and especially the rise of the computers market, computer-aided design was beginning to be extensively used for construction. CAD began in 2D during the 70s has dramatically changed by focusing more on 3D design and modeling. There are now a variety of CAD developed products on the market, certain products catering to the requirements of specific areas.
