However, it involves more than just shapes. ĬAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. In mechanical design it is known as mechanical design automation ( MDA), which includes the process of creating a technical drawing with the use of computer software. Its use in designing electronic systems is known as electronic design automation ( EDA).

The terms computer-aided drafting ( CAD) and computer aided design and drafting ( CADD) are also used. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. There are specific features for 2d vector based graphics and 3d modeling of solid surfaces.Computer-aided design ( CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. Online CAD software offers different features depending on which design process you're working on. The big advantage of using CAD compared to traditional methods for designing is that it gives flexibility to manipulate and change the design in a fraction of the time.

Traditionally, pen and scale were used for drafting only a 2d image of an object, but with CAD, a 3d image of any object can be drawn especially if you have such tool as free online cad viewer for this.

With the use of CAD it has become easy, especially for architects and engineers to design any imaginary drawing model of a building or infrastructure and to predict structural problems and find solutions even before they arise. CAD (computer-aided design) - is the use of computer systems that enables a designer to design and view anything in real time, online and with accuracy, it has become an important tool for viewing and drafting.
