Abstract
Computer-aided design (CAD) consists of using computer systems to assist the creation, modification, analysis, and optimization of a design. Initial developments were carried out in the 1960s, linked to the aeronautic and automotive industries, although it was not until the 1980s that these tools started to be used in small and midsize companies, thus reducing the need of draftsmen. Initially designs attainable with CAD tools were mainly 2D, but nowadays the use of 3D modeling packages is widespread, due to its versatility.
Nowadays it has become an essential set of tools with relevant benefits for any kind of industrial product development process, such as overall project cost and time optimization, what becomes especially relevant in the field of novel medical devices. Application fields include architecture, automotion, aeronautics, naval and mechanical engineering, automation and electrical engineering, chemical engineering and materials science, and especially linked to the purpose of this handbook, biomedical engineering. The promotion of information exchange among clients, developers, and suppliers, during a whole new product development process, is also noteworthy.
CAD is intimately connected to several additional technologies, most of them working on the basis of an initial computer-aided designed part or product, such as computer-aided engineering (CAE), computer-aided manufacturing (CAM), product data management (PDM), among others, all of them integrating the more general term of product lifecycle management (PLM) technologies.
This chapter supplies an introduction to computer-aided design and its most typical resources, details relevant connections with other computer-assisted tools, and provides different case studies linked to the development of real biodevices by using different simple CAD operations. Some current limitations and future trends, which will be discussed in following chapters, are also introduced.
