subject: Introduction To Cad [print this page] CAD refers to computer-aided design, which is a creative design process that is done using a computer system. Its software, the CAD design program, is widely used by professionals in the design field that requires much precise technical drawings. However, it is not like other drawing programs where you can simply open and begin drawing. It requires a combination of tools and mathematical equations to get started, and in order to get the design precise. As it is not easy to master the program, people are trained to become professionals in order to use the program.
Previously the CAD systems could only function on specific computers, but now they are able to function in any computer that has the suitable components connected to it. Computers with CAD typically need a high-quality graphics card, a reliable mouse, and a drawing tablet. For better results, a plotter can be used with the computer.
Most of the CAD design programs are expensive, but some cheap or free ones are also available. The cheaper alternatives, of course, come with some disadvantages, such as incomplete tools or drawing functions. For professionals, such tools can be a crucial component for the success of their job and business, which is why they would invest in the original program.
The computer-aided design and drafting programs can come in two types of dimensions, which are 2-dimensional, and 3-dimensional. The 2-dimensional drawing comes in a simpler image, where the image will only show one angle of the design.
The 3-dimensional drawing, on the other hand, is more complicated, showing other possible views and angles. Architects and engineers mainly use 3-dimensional option because their drawing will need to be detailed and precise, which cannot be shown in 2-dimension. In CAD design programs using the 3-dimension option, one can even view the different perspectives, as well as their measurements, using specific buttons. It is a complex program with simple functions that makes drawings easier to understand.
