基于CAD三维模型生成工程图的探讨与应用

本文探讨了Pro/E和AutoCAD软件相结合,由三维模型生成二维工程图的方法.在Pro/E中出二维工程图,由于其全尺寸相关的特点,避免了模型修改后工程图的二次修改,因而具有较高的设计效率;AutoCAD是工程设计人员熟悉及普遍使用的软件,具有强大的二维绘图及编辑功能,将Pro/E中的二维数据转入AutoCAD中进行标注和出图,也是一种切实可行的方法.     

基于3D CAD技术的工程制图教学改革探讨

作为工程设计和产品开发工具的三维CAD应用必将普及.3D CAD/CAM技术的发展对工程制图教学提出了严峻的挑战,工程制图教学应将传统工程制图与二维CAD、三维CAD分块进行教学,并建议组织开设课程设计,以提高用计算机建立三维产品模型和生成二维工程图的能力.     

烟草移栽机链箱的计算机设计与制造

采用UGNX7．0软件的CAD功能对烟草移栽机链箱进行实体三维建模设计,通过UGNX7．0提供的机械制图功能,自动生成二维工程图,并转换为通用AutoCAD格式,运用AutoCAD软件进行标注并生成标准CAD图纸,按图纸要求进行加工制造,在制造的过程中采用UGNX7．0提供的CAM功能进行加工仿真,生成数控代码,最终完成整个设计及制造过程,为类似产品的设计及制造提供借鉴．     

基于先进制造技术的工程制图课程的改革

高职工程制图课程为满足先进设计和制造技术的需要,应提倡设计从三维开始。在工程制图学教学中,要以计算机三维软件为平台,强调三维设计的概念;以三维实体和三维造型为主线,培养学生三维到二维的图示能力和二维到三维的空间想象能力,为学生今后面向现代的设计与制造方法的实际工作奠定基础。     

AutoCAD三维实体转二维视图方法的研讨

基于Auto LISP、Visual LISP、Dialog Control Language等程序语言,并结合AutoCAD中的flatshot命令,开发将三维实体快速生成二维视图的AutoCAD插件,为创建工程图提供了极大便利.文章重点论述了程序设计的主要方法和步骤.     

利用Inventor软件改进中职《工程制图与CAD》教学

通过介绍利用Inventor三维建模软件的建模、装配、工程图、表达视图等主要功能模块,文章提出了采用＂二维———三维———二维＂的教学过程,改进了《工程制图与CAD》教学方法 ,提高了教学质量。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
