The design is key slot, shaft coupling, gear and bearings for the design parameters of the design process, the application of the Access database, inlay in Auto cad 2004 and the Auto lisp VBA procedures, the main design concepts : using VBA common structure for the selection and design, Access databases and enquiries generated through relevant parameters instead seek out a large amount of information generated readable final text documents (including the document mapping the relevant data used), and then using Auto lisp procedures required readable text documents commonly used in the design of the structure direct mapping.

谁能帮忙翻译一下！谢了！！本设计是对键槽、联轴器、齿轮和轴承进行参数化设计，设计过程中，应用了Access数据库、嵌于Auto CAD 2004的VBA和Auto LISP程序，主要设计思想是：利用VBA对常用结构进行选择和设计，并通过查询Access数据库生成相关参数，而不用再去查找大量资料，最后生成可读文本文件（文件中包括绘图用到的相关数据），然后利用Auto LISP程序调用可读文本文件对设计的常用结构直接进行绘图。
