Research on the use, development and benefit of high-grade CAD software

1 Introduction

The role of CAD has been agreed upon. But the actual benefit of the play, in different areas of the gap is very large, especially the introduction of high-end CAD workstation system development and application, the gap is even greater. At present, some new concepts have appeared in the application and popularization of CAD technology, and some new functions and features have appeared in CAD technology. This paper focuses on the benefits and benefits of CAD, as well as the use and development of these benefits and benefits. For CAD users, CAD technology is mainly embodied in the commercialized CAD software, this paper discusses the CAD technology, mainly refers to high-end CAD software embodied in the function, the high-end here refers to the operation on the workstation, the current price of more than 100,000 yuan CAD software.

The relation of human-machine in CAD 2 and its influence on the design method

Although CAD technology has been widely used, but still can not say that CAD is a very mature technology, its concept, theory and method is still in constant development and update, CAD is the application of computer technology in the design process, but the current said CAD can not completely replace people and achieve the real meaning of "automatic design" , so it is still a system of people. In this sense, there is a problem of adaptation, matching and adjustment between people and computers.

The dominant position of the people in CAD is changed. The first development goal of CAD technology is to be a better tool, such as scale board, calculation ruler and so on. Therefore, in the early CAD technology of human-computer relations, computers are weak links, it should cater to and adapt to the design of people.

With the development of computer technology, its function and ability in the field of design are increasing rapidly. The computer can do a better job of designing tasks that are limited or even impossible to achieve in the past, which will inevitably lead to the reallocation of piles and tasks in the CAD system, and even change the way of design. In this process, the computer is gradually getting more important status by the hand design of the person. This is the old fashioned way of design and organization will only affect the function and potential of CAD software play.

3 The use and development of CAD software

If you want CAD software to produce greater benefits, you must rely on the use and development of CAD software. Different areas in the introduction of the use and development of CAD software steps, the emphasis and the way are bound to be different. But the general principle is to coordinate two relations, one is the nature and scale of the application task of CAD software and the features and functions of CAD software, and the second is the matching of the human-machine relationship in CAD system.

3.1 High-end workstation CAD software use environment for high-end workstation CAD software is divided into two situations, one is used alone to solve the project single design problems, from a technical point of view, the main use of high-end CAD software for complex shapes, precision modeling capabilities, model reuse and model to NC machining automatic programming. This application only plays a part of the potential of CAD software, and its benefit is reflected by the economic benefit of individual task.

Another application is a specific goal that is not targeted at the project. It is to establish the function of high-end CAD software from the angle of CAD system in the Application field, and to improve the overall technical quality in the field of application. If the development of CAD technology reflects the change from tool to environment, this application is more fundamental, and the difficulty and workload of using and developing is much more. The difference between environment and tool is that it has its own inherent law, and people can use and transform it effectively only on the basis of understanding it. It is in this sense that there is reason to think: CAD to study two models, in addition to product models, but also to study the design process model. The whole process of the specific design can be divided into several stages, according to the different stages of task, to determine the different grades, the purpose of the division of software, only in this way can be technically and economically reasonable and cost-effective.

3.2 The application of CAD software for CAD software should start from computer CAD, gain experience, cultivate technical backbone, and lay the foundation for the future of CAD workstation, which is generally accepted in China and abroad, but from the point of view of practical operation, this view has not been paid enough attention. The reason is that there are two misunderstandings in the understanding.

Firstly, the technical complexity and characteristics of high-end CAD software are not well understood. Thought that as long as the purchase and installation of CAD software will naturally play a role. In fact, the current high-end CAD software technology content far more than most of our users of the technical level, and even people's ideas and capabilities can not and high-end CAD software features have a minimum of matching, it will make high-end CAD system can not play a long-term role. resulting in low-end use of high-end software has greatly wasted software resources.
