DXF文件接口程序的设计及其在反求设计中的应用

THE DESIGN OF DXF FILES INTERFACE AND APPLICATION FOR REVERSE DESIGN

DXF文件是一种简单、方便、易读的图形数据转换格式。在反求设计中需将经过精度分析后的轮廓曲线、曲面转入通用CAD /CAM中以充分利用现有资源、提高设计效率。文章根据DXF格式要求,编制了一用于反求设计的DXF格式转换程序应用于实践。

DXF is a simple drawing data transfer format. In reverse engineering, in order to use to the best of existing resources and improve the design efficiency, the spline being analyzed needs transferring to the universal CAD/CAM. In this paper, we design a DXF transfer program which can be applied to the reverse design.
