摘要
分析了DXF图形交换文件、STEP中性文件和IGES初始图形交换规范三种文件结构,在此基础上介绍了前后处理器的设计原理和程序框架,剖析了处理器设计的关键技术,介绍了从DXF文件提取图形信息到SQLSERVER数据库中,并从数据库中提取数据,写入STEP中性文件;然后从中性文件中获取数据,写成IGES文件;最终实现数据共享。
Based on the analysis of drawing exchange files（DXF）, STEP neutral files and initial graphics exchange（IGES）, this paper describes design principle and program frame of processing machine and how to acquire drawing data from DXF file, move data to SQL server database, get data from database, write them into STEP neutral file, get drawing information from neutral file, receive IGES file, and realize emersion of graphics.
