文献综述杨青.docx目前，CAD技术在我国的机械行业已经相当普及，很多企业基本 上实现了无图纸化生产。当前在市场竞争日益激烈的情况下，企业若 想处于不败之地，必须以新，奇、快的产品占领市场。为了达到这个 、 装配性、力学特性等因素，只适合二维图彤处理的CAD系统已无法胜 任这些工作。因此在市场上出现了很多三维实体CAD系统，这些三维 ， 开发周期。在众多的三维CAD乐统中，以创新著称的、Windows原创 的SolidWorks软件独树一帜, 用者以熟悉的操作方式进行高效的产品设计，避免了设计人员需要花 大量时间学****软件和操作系统的局面。另电'SolidWorks开放的接口 便于和其它软件的集成，目前包括SuffaceCAM、SmarTeam和 CosmoWorks等与SolidWorks集成的应用软件达200多个，形成了以 设计自动化软件SolidWorks为核心的基于windows的cAD, cAE, cAM, PDM集成系统。
为了方便用户进行二次开发,SolidWorks提供了几百个API函 数， VisualBasic和Visualc++调用它们开发自己的应用程序。使用 Visual Basic进秆-开发时，只能采取***的工作方式，即需要在用 户的应用程序和soudworks之间进行前后台切换，所以降低了设计效 率。而使用Visual c++
开发的应用程序可以直接嵌入到solidwork 呐部，加栽成功后应用程序菜单直接出现在SoliWorks主菜单上，如 同SolidWorks自带功能一样进行工作，极大地提高了设计效率。

ABSTRACT
At present, the CAD technology has been quite popular in machinery industry in China, a lot of enterprises basically achieved without drawing increasingly fierce competition in the market situation, enterprises in an invincible position, must be new, odd, quickly occupy the market. In order to achieve this goal. The enterprise must early in the product developmentprocess, consider the product manufacturability. Factors of assembly,mechanical property, only suitable for CAD system of two-dimensional graphics processing is not up to the job. Therefore, in the market has a lot of 3D CAD system, the product model of the 3D CAD system generated. Can be directly input into a finite element analysis for the corresponding analysis, machining simulation and so on. So it can greatlyshorten the product development cycle. In many of the 3D CAD system,famous for its innovation, Windows original SolidWorks software become an independent school, SoliWorks is very powerful. It allows users to design products and efficient to ge
