A tablet is a device for placing selectable menus or modules on a separate, peripheral plate. It is helpful for a user of CAD software to have all the modules available displayed on the screen for selection. The only drawback in such an arrangement is that it takes away a portion of the screen space and therefore less space is available for the actual CAD activities. Selection of an item from a tablet can be made with a mouse or light pen (Fig. 4). 

The use of color graphics is also an effective means for displaying chemical stmctures. This method is far better than typesetting the three-dimensional architecture of complex multimolecule assembly (112). For developing in-house CAD software programs, the three-dimensional, sohd-modeling capabiUties of SdverScreen can also be utilized either in monochrome or color for constmction of such stmctures (113).

Digital Material is a new and special type of Composite Material, produced during the printing process by the selective deposition of different UV curable materials, from different inkjet nozzles, and according to a predefined Composite Material phase structure. This phase structure is design by Computer-Aided Design (CAD) software. 

Gaining from this technique requires skill with computer aided design (CAD) software, as well as the availability of a rapid prototyping machine (Exhibit 42.1). Therefore, you may need the help of someone who is versed and knowledgeable in this arena and its associated technologies.

The last type of hard copy output device isn t really a printer at all. Printers make images one line at a time and move from top to bottom during the printing process. Plotters, on the other hand, draw the image as we would, with a pen. One shape at a time. Plotters are most often used with CAD software to produce blueprints or technical diagrams. It would be quite expensive to make a printer that can print on paper as wide as these drawings require. Because a plotter uses a pen (or several pens in a holder) on a cable carrier, it is easy (and relatively inexpensive) to make a very wide plotter. A couple of typical plotters are shown in Figure 6.18.

The manufacture of the CMOS microprocessor, just like every other IC device, comprises the three phases of design, fabrication, and testing shown in Fig. 16.4. The first phase is the design phase, comprising the definition, circuit design and analysis, layout synthesis, verification, and tape-out of the microprocessor from the design house. This phase relies heavily on CAD software. 

Biomolecular three-dimensional structure database records are cmrently not compatible with macroscopic software tools such as those based on CAD software. Computer-aided design software represents a mature, robust technology, generally superior to the available molecular structure software. However, CAD software and file formats in general are ill-suited to examine the molecular world, owing to the lack of certain specialty views and analytical functions built in for the examination of details of protein structures.

Three-dimensional scanning of the human body and three-dimensional CAD software are used to help develop the design patterns for various types of sportswear. These techniques are used to create custom fit models, build life-like digital clothing samples and adjust these based on virtual fit. Based on some mechanical and physical properties of the used fabric, 3D fabric simulation software can be employed to determine how the fabric may behave and drape on the digital body model. 

First, a 3D stmcture is designed using CAD software. Data obtained from computerized tomography (CT) or magnetic resonance imaging (MRI) medical scans can be used to create a customized CAD model. This CAD model is then expressed in a series of cross-sectional layers. The complex scaffold architecture must be built using layer-by-layer (LBL) manufacturing processes known collectively as solid free-form fabrication (SFF). 

Modern CAD—an acronym for computer-aided drafting or design—has its roots in the early 1960s. Aerospace, automotive, and electronics companies first used CAD. These large companies were the only ones who could afford computers that could perform the massive calculations needed for CAD. As personal computers became affordable and CAD software became available for this size of computer, CAD became a universal application in design, manufacturing, and construction (see Figure 7-1). 

Three-dimensional models also allow engineers to test their designs before the part or product is actually made. The CAD software can also run a stress analysis on a part to determine fracture points. Engineers are able to see what their part will look like, how it will work with other parts, what materials are best to use, and whether any changes are needed in the design. 

CAD systems are also useful for estimating material costs. The CAD software will have libraries of different materials that allow an engineer to compare the cost, strength, and...
