计算机辅助设计在生产中的应用 摘要 计算机辅助设计是利用计算机及其设备帮助设计人员进行设计工作在工程和产品设计中，计算机可以帮助设计人员担负计算、信息存储和制图等项工作。在设计中通常要用计算机对不同方案进行大量的计算、分析和比较，以决定最优方案；各种设计信息，不论是数字的、文字的或图形的，都能存放在计算机的内存或外存里，并能快速地检索；设计人员通常用草图开始设计，将草图变为工作图的繁重工作可以交给计算机完成；利用计算机可以进行与图形的编辑、放大、缩小、平移和旋转等有关的图形数据加工工作。Computer-aided design in the production Summary Computer-aided design is the use of computer graphics equipment to help designers to design work, referred to as CAD. In engineering and product design, the computer can help the designer responsible for computing, information storage and mapping and other work. Usually use a computer in the design of the different options a lot of calculation, analysis and comparison to determine the optimal solution; a variety of design information, regardless of numbers, text or graphics can be stored in computer memory or external deposit, and can be quickly retrieved; designers typically start with a sketch design sketch into the heavy work of the working drawing to the computer to complete; use of computer editing and graphics, enlarge, shrink, pan and rotate about graphical data processing. With the rapid development of modern computer technology, computer-aided design CAD ??(Computer Aided Design) applications in the production of increasingly widespread, from computer-aided design in mechanical production applications described in the mechanical design, a significant advantage and the current application status and problems of the domestic enterprises of mechanical product development process of three-dimensional CAD system analysis. Starting from the actual needs of product development and product features and software functionality, enterprise applications, three-dimensional CAD process improvement program, and finally the development trend of 3D CAD technology.Keywords: computer-aided design, 3D CAD application 目 录 1 绪 论 1.1课题背景及目的 1 1.2概述 1 2 CAD技术从二维CAD向三维CAD的过渡 2 2.1CAD简介 2 2.2 三维CAD的优势 3 2.3 CAE简介 4 3 计算机辅助设计在生产中的应用 5 3.1计算机辅助设计应用于生产的优势 5 3.2计算机辅助设计在生产中的作用 6 4 计
