AutoCAD is a Computer Aided Design（CAD） prograineering and design office in the world. When you start AutoCAD， the AutoCAD window will open. The window is actually your design work space. How create a new drawing with AutoCAD? Firstly， you choose “New” from the“File” menu . The dialogue box will appear in the command window underside of the AutoCAD window. Secondly， you can choose“Start from Scratch”， under “Select Default Setting” select“English” or“Metric”， and
The engineer or designer first draws the part on the screen of computer. This part drawing is the actual part geometry . The sizes and locations are all correct so that the information can be used later to create a program to machine the part③. Actually， you can also draw the geometry of a workpiece with CAD software on a computer. You may create the design model by applying graphics commands stored in the computer. Fig.5 -1 is a typical part drawing interface of AutoCAD software. You have complete freedom to zoom and view the model at different

components， each of which provides different information of command options for the user（Fig.5 -2）.
AutoCAD界面由几个不同部分组成，每个部分都可为用户提供 不同的指令选择信息（图5 -2）。 “which”引导的非限制性定语从句修饰先行词“components”， “which”不能省略，也不能用that来代替。 provide ... for ...译为“为……提供……”。 ⑤ This diagram labels the most vital parts of the interface. 下表列出了界面上最重要的几个组成部分。 this和these常指后面将要提到的事物，有启下的作用;that和those 常指前面已经讲到的事物，起承上的作用。 例如:I will say this to you: He is an honest man.
