【摘要】：为了更好地服务于社会,深入开展“CAD技能等级”培训与考评工作。2008年中国工程图学学会联合国际几何与图学学会,组织了国内外有关专家,制定了科学、规范的《CAD技能等级考评大纲》。它将CAD技能分为两类三级,两类是指“工业产品类”和“土木与建筑类”;三级是指:一级为二维计算机绘图;二级为三维几何建模;三级为复杂三维模型制作与处理。虽然有了测评大纲参考,但相应的CAD技能测试题库却没有提供,后续技能等级测试工作不易全面展开。网上或图书中有一小部分可供参考的资料或测试卷,但比较少,不够细致、全面,与大纲中的测点不是很对应,且题库系统的开发除了测点的对应,必须查找、规范、设计、制作众多的题型,开发相应等级的多个不同单元、难度一致、内容不同的题库系统,工作量很大,显然这项工作具有重要意义,需要我们认真研究,不断深入地做好开发工作。正是在这样的背景下我们提出了“工业产品类CAD技能测试大纲分析及其题库系统开发”研究课题。本文针对大纲中的工业产品类CAD技能测试大纲的技术制图及其CAD理论和概念加以研究叙述,其后给出了客观题样题设计100题。其次针对工业产品三个级别各个测试条目的各个测点进行了详细分析,并设计了相应的技能测试题型,同时在此基础上开发了基于VB高级编程语言的“工业产品类CAD技能测试题库系统”,该系统包括三级18个单元的18种题型,开发了相应的测试题540道题集成为一个题库系统,该题库系统具有浏览、增删、搜索、修改、组卷等功能,该系统的开发成功为大量、迅速、方便地进行工业产品类CAD技能测试大纲与题库的有效衔接打下了基础,为工业产品类CAD测试的迅速、方便、客观、公平、公正提供了基础。同时可以大大促进CAD技能测试的网络化、电子化、无纸化、标准化、自动化。
[Abstract]:In order to better serve the society, the training and evaluation of "CAD skill level" were carried out in depth. In 2008, the Chinese Society of Engineering Graphics, together with the International Society of Geometry and Graphics, organized relevant experts at home and abroad and formulated science. Standard outline of CAD skill rating. It divides CAD skills into two categories and three levels, two types are "industrial products" and "civil and architectural classes"; three levels are: one is two-dimensional computer drawing; the second is three-dimensional geometric modeling; and the third is complex three-dimensional model making and processing. Although there is a reference to the evaluation outline, the corresponding database of CAD skill test questions is not provided, and the subsequent skill grade test work is not easy to carry out in an all-round way. There is a small part of the materials or test papers available for reference on the Internet or in books, but they are less, less detailed and more comprehensive, not very corresponding to the test points in the outline, and the development of the test bank system, in addition to the correspondence of the test points, must be looked up, standardized, and designed. It is of great importance to make a lot of questions and to develop several different units of corresponding grades. The difficulty is the same and the content is different. It is obvious that this work is of great significance and needs us to study it carefully and to do the development work in depth. It is under this background that we put forward the research subject of "the analysis of CAD skill test outline and the development of test database system for industrial products". In this paper, the technical drawing of industrial product CAD skill test outline and its theory and concept of CAD are studied and narrated, and then an objective sample design of 100 questions is given. Secondly, the test points of each test item of three levels of industrial products are analyzed in detail, and the corresponding skill test questions are designed. At the same time, based on VB advanced programming language, the "Industrial Product CAD skill Test question Bank system" is developed. The system includes 18 kinds of item types of 18 units of three levels, and the corresponding 540 test questions are integrated into a question bank system. The system has the functions of browsing, adding, deleting, searching, modifying, composing and so on. The successful development of the system has laid the foundation for the effective connection between the test outline of CAD skills of industrial products and the test database. It provides the foundation for the industrial product CAD test to be quick, convenient, objective, fair and impartial. At the same time can greatly promote CAD skills testing network, electronic, paperless, standardization, automation.
