CAD or computer aided design is the name given to a range of software packages used in graphic design. CAD packages are used for drawing plans for architectural structures, engineering briefs and technical illustrations. Using CAD packages graphic designers can create accurate designs and models in relatively little time. Software packages allow designers the flexibility to create and edit detailed designs in 3D and 2D forms to suit differing presentations.
The following information summarises some of the key aspects of computer aided design.
Structural Computer Aided Design
CAD programs have been used by architects for some time to draw up plans for a range of structures. Using software packages architects and surveyors can get an impression of how a structure will look as the design progresses.
Using these programs architects can enter a range of variables that will affect the design and use the results to make a realistic model resembling the final build. A range of CAD programs are available at industry levels for professionals in the field. Depending on the specification of the design different packages may offer specific benefits over other programmes. From these initial designs blueprints can eventually be drawn up to implement in the final design of the building or structure.
Simplified software packages for structural design are also available to purchase and download for domestic use. Home design software packages allow users of varying levels of computer literacy the opportunity to plan out sections of their homes with relative ease. Although the end product may not be at a level comparable to an architects work the initial workings can be taken to a professional to develop into a working model.
Automotive CAD
CAD has been used in the design process of making cars and vehicles for some time. Using computer aided design techniques designers can input dimensions and ideas from brainstorming and sketches to implement as a 3D model.
Once the designer has been sufficiently trained this method of designing can be much more efficient than traditional pen and ink methods. As a model can be continually updated and tested on screen using mathematical equations a single designer can work on a concept without the distraction of having to redraw sketches and input formulae manually.
Using CAD software a range of structural and design elements can be assessed by graphic designers. The results generated can then be implemented into prototype models for physical testing and evaluation.
