航空航天产品的生命周期通常超过70年，工程图纸归档与长期保存对于航空航天产品来说十分关键。目前，许多企业正在将传统的2D工程图纸替换到更加先进的3D标注模型。因此，研究如何长期保存3D条件下的产品定义数据十分必要和迫切。本文讨论了带有几何图形、尺寸公差以及其他规格信息的3D标注模型长期归档保存问题，分析了国际上3D标注模型长期归档项目的研究状况，并提出一种符合国内航空工业的归档思路。

The life cycle of aerospace prod-uct development usually exceeds more than 70 years. Archiving and long-term preservation for engineering drawings is critical to aerospace products. At present, many enterprises replace the traditional 2D engineering drawings with 3D annotated CAD models. Therefore, it is necessary and urgent to research how to maintain product deifnition data over such a long period of time. The problems of long term archiving of 3D models an-notated with geometric and dimensional tolerances, and other specifications are studied.The status of interna-tional long-term archiving project analyzed, and a po-tential archiving idea for domestic aviation industry is proposed.
