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 benefits 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 time of its implementation. It should be noted that depending on the objectives and scope, various 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 personnel matters, technical and software tools and other implementation features. Here it is necessary to stop 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 productsCAD is aimed at solving a number of problems in the issue of achieving the required result. They are used in 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 automation systems perform the following tasks:

1. Reduction in terms of project creation;
2. Reducing the complexity of planning;
3. Reducing the cost of doing calculations and minimizing costs in the creation of something and its operation through the selection of 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 compound structural parts. In this case, 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 part of the whole, which has been allocated for certain essential characteristics. They should 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 characteristics:

1. Serving subsystems. These are object-independent formations thatperform functions that are common to 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. This means a set of interconnected and interacting mechanisms and devices (peripherals, measuring aids, communication lines, network equipment, computers).
2. Mathematical support. This includes methods, algorithms and models that are used to obtain the result.
3. Software. It is divided into four subspecies: applied, system-wide, informational and linguistic.

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

Conclusion

CAD systemsare an extremely interesting topic. Information about these developments is primarily useful for those who are thinking about starting their own business, which will be to develop complex machines, work with a large number of details, create designs, and so on, or is involved in complex calculations. You can also direct your strength to the end in order not to receive an automated, but an automatic system. Already we can predict that a person (or organization) who does so will be able to make good money from it.
