CAD software is used by architects and engineers to design 3D objects. It has revolutionized the design industry with its functions of multidimensional imaging, computer animation, and computational geometry. It has eliminated drafting and design work, and a new role of CAD designer has developed. Training is now incorporated into every program for engineers, architects, and designers, and the price has dropped significantly.
Computer-aided design software, or CAD, is a modeling tool used by architects and engineers to design three-dimensional objects. This software is used to create new products or deepen understanding of existing products. While best known for working with shapes, this type of software has all the standard symbols required for engineering drawings and schematics. There are four key characteristics of CAD software: functionality, industry impact, training, and price.
There are three functions in CAD software that revolutionized the design industry: multidimensional imaging, computer animation, and computational geometry. Multidimensional images require curves, surfaces and solids, all of which are very difficult to create on a computer screen. The physical drawing of these shapes requires artistic training and the use of shading to indicate other dimensions.
The CAD software allows images to be rotated 360 degrees, giving designers the opportunity to model the entire object much faster and without the need to physically render the item first. The computer animation aspect has impacted both the entertainment industry and engineering. In entertainment, it has enabled the development of higher quality cartoons and commercials. In engineering, both form and function can be modeled, and any design flaws can be seen and corrected, before a physical prototype is created. Computational geometry and industrial art have also taken advantage of the functions available in this tool to create a new type of sophisticated product that best suits their unique needs.
The adoption of CAD software has resulted in the elimination of a large number of drafting and design work. Entire departments could be replaced with a single software package. Engineers and architects have been required to learn the software and incorporate different tasks into their jobs. Over time, a new role of CAD designer has developed. This person has an advanced level of expertise with software and can act as a consultant to other designers and engineers.
CAD software training is now incorporated into every training program for engineers, architects and designers. Specialized courses in specific software and advanced features are available on a part-time basis at a variety of community and career colleges. It’s very important to keep these skills up-to-date, as software is constantly updated and changes over time.
The price of CAD software has dropped significantly as computer memory usage has increased and the size of computer memory has expanded. The software now offers complex and highly advanced features for the same price as the basic version of three years ago. These tools allowed new theories to be tested and options explored before continuing.
