摘要
基于对AutoCAD的DXF文件格式的详细分析 ,充分利用多义线的表达简洁性优点 ,并结合冲压件自身特点 ,提出了冲压件几何信息获取的方法及程序框架 ,详细说明了几何信息库的创建方法 ,并进一步采用Delphi6.0语言编程 ,实现了冲压几何信息库的建立和几何信息自动提取。
Based on the particular analysis of DXF file format in AutoCAD,fully taking advantage of the compact expression of polylines,and combining the characteristic of punching parts, a method and program frames used for extracting geometric information of punching parts were proposed,and the method of creating geometric information database was elaborated. Geometric information database and the program of automatic extracting geometric information were implemented by Delphi6.0.
