【摘要】 STL文件是CAD系统与快速成型制造系统之间进行数据交换的标准格式文件,由于CAD系统在生成STL文件时使用的转换方法不当,使得由STL文件描述的实体模型有许多缺陷,要修复缺陷建立实体模型的拓扑关系是必要的。该文首先对STL实体模型进行了拓扑关系重建,然后修复了一些实体模型中常见的缺陷。更多还原

【Abstract】 STL file is the data exchange standard between CAD system and rapid prototyping manufacturing system. Due to improper transformation method when generating STL file, solid model described by a STL file has many errors, topological relationships is very necessary to repair them. This paper first establishes topological relationships for STL solid, and repairs some familiar errors.更多还原
