Human ingenuity has given us architectural marvels like the Seven Wonders of the Ancient World, the Stone Henge, Angkor Wat, Machu Picchu and the Great Wall of China. It also built the first aeroplane, the Titanic, the Model T, the German U Boats and V1 missiles, and inspired the first space adventures. All of them before the advent of computer. One cannot therefore say that sophistication is a boon from the computer only. However, design and manufacturing depended on scale models and prototypes, excruciating drawings on huge pages, and a lot of trial and error. The advent of the Computer Aided Design and the Computer Aided Manufacturing made the processes much simpler, more logical, and more amenable to corrections and review.
Computer-aided design (CAD) is the use of computers tools that create computer structural models which help engineers, architects and other design professionals in their design and construction work. As a geometry authoring tool it is used within Product Lifecycle Management process. Many of the contemporary CAD software incorporate 2D vector drawing modules and 3D solid and surface modelers. CAD is used to design and develop products, these can be goods used by end consumers or intermediate goods used in other products. CAD is also extensively used in the design of tools and machinery used in the manufacture of components.
CAD is used throughout the engineering process from conceptual design and layout, through detailed engineering and analysis of components to definition of manufacturing methods. Integrating computer-aided manufacturing (CAM) with computer-aided design systems produces quicker and more efficient manufacturing processes. This methodology is applied in different manufacturing areas. Today, CAD/CAM is used extensively for all sorts of designs, from printed circuit boards to the fuselage of planes.
CAD/CAM is an expert service. There are special service bureaus providing customized CAD/CAM solutions for clients. There are numerous software solutions available, many of them running on standard desktop computers, that have enabled all engineers, architects and designers to avail of computer modeling.
In this section of the directory, we provide you with a list of links to service bureaus providing various design solutions, and design platforms and software for all your design and modeling needs.
