介绍了OCAD(optical CAD)光学设计软件包与国内外其他著名光学设计软件，如美国ORA公司的CodeV，Focus Software公司的Zemax，还有OSLO、LENSVIEW、ASAP和TRACEPRO等，以及国内SOD88等的链接及互动方法。指出OCAD光学设计软件包本身不仅具有光学设计软件最基本的功能，而且可以利用自身功能界面随时调用上述软件程序为其所用，做到各程序间有效链接，行为互动；OCAD光学设计软件包还可以和文字处理及工作报表等通用程序，如Word和Excel等程序进行链接和互动。针对我国光学设计和光学制图的国家标准，部颁标准及企业标准推出了面向国内的OCAD光学设计软件包。提出目前国内外有关光学设计软件的功能及特点已非常丰富，没必要重复研制内容相同的新软件，只有针对自身的特殊需要研制一些专用应用软件即可。

The paper introduces a method for the optical design software package OCAD to link and exchange data with other frequently used optical design softwares developed both in China and other countries,such as Code V by ORA and Zemax by Focus Software in US,as well as Oslo,LENSVIEW,ASAP,TRACEPRO and domestic software SOD88. In addition to the basic functions of the optical design software,the OCAD optical design software package could call the above-mentioned design softwares on its function interface,implement links and data exchange between different softwares. It can also link and interact with frequently used word processing programs or operational chart programs,such as Word and Excel. By combining available functions and characteristics in the existing softwares,what we need to do is just to develop a professional software aiming at our specific requirement. Based on Chinese standards (GB),industry standards and enterprise standards,the optical design software package OCAD is developed.
