CAD” and “CADD” redirect here. CAD 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. CAD output is often in the form of electronic files for computer hardware design pdf, machining, or other manufacturing operations. Its use in designing electronic systems is known as electronic design automation, or EDA.
CAD 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. However, it involves more than just shapes.
