product designing.1.What is the complete form of CAD?Can you 2.say something about CAD?2.How can CAD help designers to achieve efficient design?Reading AUnit 3Product DesigningComputer-Aided Design(CAD)Computer-Aided Design(CAD)is the use of computer technology to aid in the design and particularly the drafting of a p a r t o r p r o d u c t.N o w a d a y s,C A D h a s b e c o m e a n especially important technology,which greatly improves work efficiency compared with hand drafting.It has many benefits such as lowering product development costs and shortening the design cycle.CAD enables designers to lay out and develop work on screen,print it out and save it for f u t u r e e d i t i n g,t h u s s a v i n g t i m e o n t h e i r d r a w i n g s.Reading AUnit 3Product DesigningReading A There are several different types of CAD.Each type requires the operator to think differently about how he will use it and design virtual components in a different manner.There are many producers of the lower end 2D systems.These provide an approach to the drawing process without the trouble on scale and placement on the drawing sheet that accompanied hand drafting,since these can be adjusted as required during the creation of the final draft.With their help,designers do not need to worry about scale and placement on the drawing sheet.Unit 3Product DesigningReading A 3D wireframe is basically an extension of 2D drafting.Each line has to be manually inserted into the drawing.The final product has no mass properties associated with it and cannot have features directly added to it.3D“dumb”solids are created in a way similar to controlling real world objects.Basic three dimensional geometric forms have solid volumes added or subtracted from them,as if assembling or cutting real world objects.Two-dimensional projected views can easily be generated from the models.Unit 3Product DesigningReading A 3D parametric solid modeling requires the operator to use what is referred to as“design intent”.The objects and features created are adjustable.Any future modifications will be simple,difficult,or nearly impossible,depending on how the original part was created.If a feature was intended to be located from the center of the part,the operator needs to locate it from the center of the model,not,perhaps,from a more convenient edge or any point,as he could when using“dumb”solids.Parametric solids require the operator to consider the consequences of his actions carefully.Unit 3Product DesigningReading A In principle,CAD could be applied throughout the design process,but in practice its impact on the early stages has been limited because sketches are widely used at that time.There are some new software programs currently available for these stages.It remains to be seen how effective they will be and how widely they will be implemented.Unit 3Product DesigningTask 2 Read the passage and match the items on the left with their features on the

有诸多益处，如降低产品开发成本、缩短设计周期等。CAD 使设计者能在屏幕上设计、完善作品，将它打印出来，或储存起来以便将来编辑，节省了制图的时间。Unit 3Product DesigningLanguage Points CAD 分几个种类。每一种都要求操作者进行不同的思考，他得考虑要怎样运用这些类型，并以怎样不同的方式来设计虚拟元件。低端的二维系统有很多源程序。这样，在最终图纸的设计过程中由于可以随时按要求调整，就避免了手绘图纸在范围和布局上的麻烦，提供了一种新的路径。有了它们的帮助，设计者就不必担心图纸的范围和布局。Unit 3Product DesigningLanguage Points 三维线框基本上是二维制图的延伸。每根线条都得手工加入。最终成品没有与之相关的质量属性，也不能直接加入特征。创作三维实体建模类似于控制现实世界中的物体。基本的三维几何形模型都可以在上面加上或减去实体积，就像组合或切割现实的物体。从这些模型中能很容易地生成二维投影视图。Unit 3Product DesigningLanguage Points 三维参数化实体建模要求操作者运用所谓的“设计理念”。创作的客体和特征都可以调整。将来的改动是简单、困难，还是几乎不可能，都有赖于原部件的创造方式。如果要从部件的中心来定位某一特征，那么操作者就得从模型的中心来定位它，而可能不是像使用实体建模时那样，从一条近便的边或任意一点去定位。参数化实体建模要求操作者要考虑清楚行为的后果。Unit 3Product DesigningLanguage Points 原则上，整个设计过程都可以用到CAD，但实际上，它在初期的作用有限，因为那时大量用到的是草图。如今有几个新研制的软件可用于设计初期。不过，它们效用如何，运用范围多广，尚待分晓。Unit 3Product DesigningTask 1 Listen to the conversation and match the people with the correct

phases.BecauseListeningUnit 3Product Designingv ScriptListeningSteven:How do you proceed with your design,Peter?Peter:Im working on the 3D Color Renderings.Steven:What kinds of software do you use?Peter:I use SolidWorks,PhotoShop and PhotoWorks.Steven:It seems you are really good at it.Peter:I know a qualified designer should have a good command of CAD.Steven:You are right.It provides a window to the future appearance of the new product.Peter:Ill finish the 3D Color Renderings the day after tomorrow.Unit 3Product DesigningListeningSteven:Good.Then,you can pay attention to Graphic User Interface.Peter:Sounds cool.But Im not familiar with it.Why do we need that?Steven:You know,it is necessary to develop a user-friendly product.Peter:Then,what should I hand in for this part?Steven:Well,you need to hand in a 2D Graphic Design and 3D Interactive Analysis.Peter:OK.Its really a laboring project.Steven:Also you need to remember that graphic design refinements are made throughout the design and development stages.Peter:Thanks for reminding me.Unit 3Product DesigningTask 5 Steven Baker presents the design to George White.Listen to the short passage and take notes
