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.
Whereas in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2D CAD system allows a copy of the original to be modified, saving considerable time. 2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide ...
One goal of CAD is to allow quicker iterations in the design process; [9] another is to enable smoothly transitioning to the CAM stage. [10] Although manually created drawings historically facilitated "a designer's goal of displaying an idea," [11] it did not result in a machine-readable result that could be modified and subsequently be used to directly build a prototype.

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.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
Illustration of the interaction of the various computer-aided technologies. CAx tools in the context of product lifecycle management. Computer-aided technologies (CAx) [1] is the use of computer technology to aid in the design, analysis, and manufacture of products.
An engineering technician is a professional trained in skills and techniques related to a specific branch of technology, with a practical understanding of the relevant engineering concepts. [1] Engineering technicians often assist in projects relating to research and development , or focus on post-development activities like implementation or ...
