Traditional drafter at work A drafter in Portugal in the 1970s, using a drafting machine. A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman, drafting technician, or CAD technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or CAD designs for machinery, buildings, electronics ...
Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [ 1 ] : 3 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.
CAD systems may be interconnected with automatic vehicle location systems, mobile data terminals, office telephones, and selective calling and push-to-talk ID.. Computer-assisted dispatch systems use one or more servers located in a central dispatch office, which communicate with computer terminals in a communications center or with mobile data terminals installed in vehicles.
It is included with computer-aided design (CAD) and computer-aided manufacturing (CAM) in a collective term and abbreviation computer-aided technologies (CAx). The term CAE has been used to describe the use of computer technology within engineering in a broader sense than just engineering analysis.

Engineers must weigh different design choices on their merits and choose the solution that best matches the requirements and needs. Their crucial and unique task is to identify, understand, and interpret the constraints on a design in order to produce a successful result. Good problem solving skills are an important asset for engineers.
However, with the advent of CAD and solid modeling software, the design engineers may create the drawings themselves, or perhaps with the help of many corporate service providers. The next responsibility of many design engineers is prototyping. A model of the product is created and reviewed. Prototypes are either functional or non-functional.
A technician can quickly build a prototype (and make additions and modifications) using these techniques, but for volume production it is much faster and usually cheaper to mass-produce custom printed circuit boards than to produce these other kinds of prototype boards. The proliferation of quick-turn PCB fabrication and assembly companies has ...
