摘 要：

CAD技术，不但让技术人员甩掉了图板，而且大大的提高了产品设计和更新速度。在其推动下，图形教学也获得了革命性的发展。大量优秀的三维模型不但给老师教学带来方便，而且对于学生学习起到了相当重大的帮助作用。为了更好地发挥虚拟模型的优势，虚拟模型库的建设应运而生。

论文介绍了虚拟现实技术的概念﹑发展情况及研究现状，CAD技术的国内外发展情况及趋势，虚拟模型在计算机辅助教学中的优势，虚拟模型库的开发现状以及虚拟模型的制作流程；说明了三维CAD软件和二维的不同，列举并比较了几种常见的三维设计软件，列举了虚拟模型的几种常用格式以及各自特点；并用实例形式详细介绍了如何用UG制作虚拟模型，如何实现格式转换等后期制作。

Creating of the Fodders for the Virtual Models’ Storeroom

Abstract

The technology of CAD not only helps technicians put down their tracers,but also improves the pace of the product’s designing and updating greatly.Thanks to its development, the graphics education receives revolutionary progress.Numerous excellent three-dimensional virtual models not only conveniences the teachers ,but also helps the students enormously .For exerting the virtual models’ advantages ,the creation of the virtual model storeroom is needed.

The paper introduces the technology of the virtual reality and its development and research conditon , the development and orientation of the CAD in our country and overseas, the virtual models’ advantages in the computer aided education, the actuality about the virtual model storeroom and the virtual models’ making flow. It explains the differences from the three-dimensional designing software and the planar one, and enumerates several three-dimensional designing softwares and compares them with each other. It also enumerates the virtual models’ several formats in common use and each one’s peculiarity. It detailedly illustrates how to make virtual models with the software of UG.and how to complete the later work as how to convert to the needed formats.

Key words: virtual reality,CAD, virtual model, UG，Spinfire,Cult3D
