【摘要】 用于快速成形系统最一般的输入接口文件是工业上默认的的表面三角化数据格式文件（ＳＴＬ文件）。由于ＳＴＬ文件格式本身以及从ＣＡＤ软件到ＳＴＬ文件格式转换过程造成的问题，所产生的ＳＴＬ文件难免有少量的缺陷。本文具体分析了ＳＴＬ文件格式的常见缺陷，并给出面片丢失的解决方法。用ＶｉｓｕａｌＣ＋＋语言易于实现。更多还原

【Abstract】 Abstract The most commonly used input to a rapid prototyping (RP) system is the de facto stereolithography file(STL). STL files exist some problems,due to the nature of STL files and the tessellation algorithms switched from CAD model to STL model.In this paper,STL files errors are discussed in detail.The paper also proposes a generic solution to solve the problem of missing facets.It’s easy to perform this solution with Visual C++ software.更多还原
