虚拟装配中模型转换的研究

The Research of Model Convert in Virtual Assembly

介绍了STEP和Open Flight两种数据格式,分析了它们之间的内在差异,并以内燃机活塞为实例,探讨了CAD模型转换成虚拟装配模型后数据丢失的部分原因,提出了相应的解决办法。

This paper introduces STEP and Open Flight, analyzes their inner different. Regarding the piston set of the engine as the applied object, the author discusses some reason about data loss during CAD data converting to virtual model, puts forward the resolve.
