Evolving Drafting Practices With CAD Drafting Programs
Drafting was once a process which required great artistic ability and training. With modern CAD drafting programs, however, the ability and training no longer focuses on being artistically inclined, but rather aesthetically inclined with a practical understanding of the uses of the product. Gone are the days where one hoped the drafter had nice handwriting in order to understand what was being explained on the blueprint, and here are the days where blueprints are handled by computers. Gone are the days where testing a product meant building the product, and here are the days when computers can test a product in a matter of minutes versus days.
CAD drafting programs are used throughout the world in many types of industry. CAD programs are used in many ways, in many fields. The drafting programs of today can take the blueprints and drafting notes of history and put them into modern blueprints and annotations. The CAD drafting programs of today are capable of taking a two-dimensional object and creating a photographic-quality three-dimensional rendering. CAD drafting programs are also able to take a 3D figure and break it apart into 2D renderings, or even reverse engineer the 3D figure. The current and latest technology associated with CAD drafting software programs is the ability to run simulations and testing programs to ensure the product works without having to run a trial and waste time and money on a failed project.
Before CAD drafting programs became popular, blueprints were done by hand, using strait-edges and compasses. The various equations needed to provide the dimensions of each aspect were usually done on scrap paper or next to the rendering. The blueprints themselves took quite a while to design and manufacture. Each change required its own annotation, written by hand, and if a change was created later, a completely new blueprint needed to be drawn. This was a very time-consuming aspect of manufacturing that often held back production of new products or bottle-necked the design and manufacturing of new products.
Before CAD drafting programs became popular, the idea of taking a 2D project and turning it into a 3D rendering often meant sculpting the product out of foam, casting it in plastic and finishing it. While this method is still employed by various companies, a faster and more efficient method has been born. This method has several manors in which it can take shape. First, there is the rendering of a 2D object in 3D life by using photo-quality imagery on the computer, complete with the ability to print these photographs. A second method is when the computer itself, operating a laser or other manufacturing device, creates the product for viewing. This is only a temporary model of the product, not often a finished product. These features, once only dreams of hands-on designers, are now realities, and keep the drafting world evolving into the CAD drafting world.
No matter what type of CAD drafting application, there are many different software programs available to handle the manufacturing situation.
