2D drafting methods are not able to relay the quality and quantity of design information because 2D methods will always rely on human interpretation or visualization skills to interact with a 2D design. This is always difficult for non design staff and almost impossible for computer systems to extract this kind of information, because computers do not have the ability to interpret.
As a result, many human errors can occur with traditional 2D design methods. In the past problems such as component collisions, incorrect quantities or parts that don't fit, would happen because a designer who works in only 2D is forced to hold much of the information mentally.
Reducing human error by using the 3D modeling design methods minimizes the need for re-work because the design quality is greatly improved. Using 3D design modeling greatly improves design quality because it is a more complete process than 2D design. One most important thing about 3d CAD design is that people can have view of the model from all possible dimensions. It is a highly detailed drawing of what your concept will look like as a finished product.
Whether you're designing a new innovative product, creating technical manuals, or requesting quotes from suppliers, 3D CAD design is extremely powerful. But when a 3D CAD design is transformed into a physical 3D print or job shops’ product prototypes, there is no substitute for the tactile and visual feedback a physical model provides to all participants in the design process.
Mechanical Designers usually share their work space with drafters or other engineering technicians in quiet, well-lighted surroundings separated from production areas. Working from drawings, sketches, planning sheets, and other engineering and shop data, tool designers must visualize the Design, do the panning, document and verify every step of the way.
Because of reductions in defense spending, jobs for mechanical engineering type work will decrease; however, the employment of mechanical engineers is expected to grow about as fast as the average for all occupations through this year due to the demand for new and more complex industrial machinery and tools resulting from the development of more sophisticated automated production processes.
The use of 3D modeling technology is essential when you want to develop a superior product. Such a product will not be influenced by human interpretation. Furthermore, it will look like the final model.
