Computer-aided design (CAD) refers to using computers (or workstations) to aid in the creation, analysis, modification, or optimization of a design. CAD design services and software are used to increase the productivity of designers, improve the quality of designs, improve documentation, and create a database for manufacturing.
Designs made through CAD software and CAD design services help protect products and inventions when used in patent applications. CAD output is in the form of electronic files for printing, machining, or other manufacturing operations. You may also see the term CADD (computer-aided design and drafting) also used.
CAD software for mechanical design uses graphics to depict traditional drafting objects or the overall appearance of designed objects. However, it involves more than just shapes. Like manual drafting of technical and engineering drawings, CAD design services convey information like materials, dimensions, tolerances, and processes.
CAD is an important industrial art used in many industrial applications, including automotive, shipbuilding, and aerospace industries, prosthetics, industrial and architectural design, and many more. CAD design services are widely used to produce computer animation for special effects in advertising and technical manuals and even in movies.
