What is CAD? Computer aided design systems: classification, practical application

What is CAD and what are they used for? What is the purpose of their application? What are the features and advantages of computer-aided design (CAD) systems? Here is a short list of questions that will be considered in the framework of this article.

general information

First, let's look at what CAD is. This is understood by automated systems that take on the implementation of information technology for the performance of the design function. They are an organizational and technical tool. With the help of CAD design is transformed into an automated process, which allows you to get a win in the quality of work and the timing of its implementation. It should be noted that, depending on the objectives and scope, different requirements may be put forward for carrying out activities. Thus, the design and construction of mathematical calculations is different when creating from architectural documents in matters of personnel, technical and software tools and other features of implementation. Here it is necessary to stop the attention on certain technical features. It should be understood that, despite its name, no CAD system is in the full sense of an automatic system. The presence of such a concept implies that everything is performed directly by technology. But in real conditions some of the functions have to be performed by a person. Therefore, in the general plan only separate procedures and design operations are automated.

Goals and objectives

During its life cycle, the work of CAD products is aimed at solving a number of problems in order to achieve the desired result. They are used at the design stages, as well as directly preparing the production. The most important goal of CAD implementation is to increase the efficiency of engineers. If we split it into more detailed components, then we can say that the automation systems perform the following tasks:

1. Reduction of the terms of project creation;
2. Reducing the complexity of planning;
3. Reducing the cost of performing calculations and minimizing costs when creating something and its operation by choosing the optimal ways of implementation;
4. Improvement of quality and technical and economic indicators of the design result;
5. Reducing the costs that go to full-scale modeling and the necessary tests.

CAD subsystems

These are composite structural parts. At the same time, their peculiarity is that they possess all the properties of the original systems and can act independently. To understand what CAD is better, you need to understand them. So - these subsystems are a part of the whole, which was allocated for certain significant features. They must be able to perform certain functionally completed task sequences with obtaining the necessary decisions and documents. Subsystems are divided into serving and projecting. Each of these species has its own peculiarities:

1. Serving subsystems. These are object-independent formations that implement functions that are common to a part of the technical integrity (or for it all). So, they are engaged in ensuring the operation of systems, design, transmission and output of data, software maintenance and so on. Alternatively, they can be called a CAD wrapper.
2. Projecting systems. These are object-oriented formations on which a certain stage of calculations or a group of related tasks is entrusted.

Security

So, we have already considered what CAD is. Now let's pay attention to the inner stuff, thanks to which their useful activities are carried out. So, designing and building models is possible because of:

1. Technical support. By this means a set of interrelated and interacting mechanisms and devices (peripherals, measuring aids, communication lines, network equipment, computers).
2. Mathematical support. This includes the methods, algorithms and models that are used to obtain the result.
3. Software. It is divided into four subspecies: applied, system-wide, information and linguistic.

Depending on how the software was implemented, the CAD classification is also carried out . This, in turn, depends on the goals that are being pursued by the developers.

Conclusion

Computer-aided design systems are an extremely interesting topic. The information on these developments first of all will be useful to those who are thinking about starting their own business, which will consist in the development of complex machines, work with a large number of details, create designs and so on, or deals with complex calculations. You can also direct your efforts to get in the end not an automated, but an automatic system. Already, one can predict that a person (or an organization) who does this will be able to make good money on this.
