What is CAD and what are they used for? What is the purpose of their application? What features and benefits do CAD systems have? Here is a short list of issues that will be addressed in this article.
general information
First, let's look at what CAD is. By this we mean automated systems that take over the implementation of information technology for the design function. They are an organizational and technical tool. With the help of CAD, design turns into an automated process that allows you to get a gain in the quality of work and the time it takes to complete. It should be noted that, depending on the goals and scope, various requirements may be put forward for carrying out activities. So, the design and construction of mathematical calculations differs when creating from architectural documents in matters of personnel, hardware and software, and other implementation features. Here it is necessary to stop attention on certain technical features. It should be understood that, despite its name, not a single CAD system in the full sense is 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 a person has to perform. Therefore, in general terms, only certain procedures and design operations are automated.
Targets and goals
During its life cycle, the work of CAD products is aimed at solving a number of problems in achieving the desired result. They are used at the design stages, as well as directly pre-production. The main goal of CAD implementation is to increase the efficiency of engineers. If we break it down into more detailed components, then we can say that automation systems perform the following tasks:
- Reducing the timing of creating projects;
- Reducing the complexity of planning;
- Reducing the cost of performing calculations and minimizing costs when creating something and its operation due to the choice of optimal implementation paths;
- Improving the quality and technical and economic indicators of the design result;
- Reduction of expenses spent on full-scale modeling and necessary tests.
CAD Subsystems
These are integral structural parts. Moreover, their feature is that they possess all the properties of the original systems and can act independently. To understand what CAD is better, you need to deal with them. So - these subsystems are part of the whole, which was identified by certain essential features. They should be able to perform certain functionally complete sequences of tasks with the receipt of the necessary solutions and documents. Subsystems are divided into service and design. Each of these species has its own characteristics:
- Serving subsystems. These are object-independent formations that are engaged in the implementation of functions that are common to part of the technical integrity (or to all of it). So, they are engaged in supporting the activities of systems, design, transmission and output of data, software maintenance and so on. Alternatively, their combination may be referred to as a CAD shell.
- Design systems. These are object-oriented formations that are assigned a certain stage of calculations or a group of related tasks.
Security
So, we have already examined what CAD is. Now let's pay attention to the internal filling, thanks to which their useful activities are carried out. So, the design and construction of models is possible due to the presence of:
- Technical support. By this we mean a set of interconnected and interacting mechanisms and devices (peripheral devices, measuring instruments, communication lines, network equipment, computers).
- Mathematical support. This includes methods, algorithms and models that are used to obtain the result.
- Software. It is divided into four subspecies: applied, system-wide, informational and linguistic.
Depending on how the collateral was implemented, CAD is also classified. This, in turn, depends on the goals pursued by the developers.
Conclusion
Computer aided design systems are an extremely interesting topic. Information on these developments is primarily useful to those who are considering starting their own business, which will consist in developing complex machines, working with a large number of parts, creating designs and so on, or doing complex calculations. You can also direct your efforts to get, as a result, not an automated, but an automatic system. Already now it is possible to predict that a person (or organization) who does so will be able to make good money on this.
