针对 CAD 与虚拟装配环境 XNA 之间的信息转换问题，提出了一种模型信息转换技术。构建了一种面向虚拟装配的层次化装配信息模型，该信息模型由产品层、子装配体层、零件层、特征层、几何层、三角面片层六层拓扑结构组成；根据模型信息分解方法，将模型信息分解为几何信息、装配信息以及面片信息等，使用 Pro ／ToolKit 二次开发工具实现了对模型装配信息的提取，并通过对模型面片信息的转换，解决了 CAD 系统与 XNA 虚拟装配环境间的信息转换问题。利用构建的 XNA 虚拟装配平台对该技术进行了验证。

To realize the information transformation between CAD and XNA virtual environment , an information transformation method of the model was proposed .Firstly ,a hierarchical assembly in-formation model for virtual assembly was constructed ,which consisted of six hierarchy layers ,inclu-ding product layer ,assembly layer ,part layer ,feature layer ,geometry layer ,triangle facet layer .Sec-ondly ,based on the information separation method ,the model information was divided into geometry information ,assembly information ,facet information and other information ,and the assembly informa-tion was extracted by Pro /ToolKit secondary development tool ,then with the transformation of model facet information ,the information transformation between the CAD and XNA was solved .Finally ,a virtual assembly platform in the XNA was developed by programming ,and a real assembly example was held to verify this method .
