基于STEP中性文件的船舶图形交换技术的研究

Ship Graphics Exchange Technology Based on Step Neutral Files

在分析DXF图形交换文件 ,STEP中性文件和IGES初始图形交换规范结构的基础上 ,介绍了从DXF文件中提取图形信息到SQLServer数据库中 ,并从数据库中提取数据 ,写入STEP中性文件。最后从中性文件中获得图形信息 ,得到IGES文件 ,实现图形的再现。

Based on the analysis of drawing exchange files(DXF), STEP neutral files and initial graghics exchange specification (IGES) , this paper described how to acquire drawing data from DXF file and move data to SQL Server database ,then get data from database and write them into STEP neutral file, finally get drawing information from neutral file, receive IGES file , and realize emersion of graphics.
