Based on the DXF file formats and combined with VC++ graphic processing and data management technology,a data exchange interface program is developed which realizes transfer of CAD graphics in VC++ program as well as subsequent development.

• 根据DXF文件格式；结合VC++技术的图形处理、数据管理功能；本文开发设计出数据交换接口程序；可以在VC++程序中实现对CAD图形的调用以及二次开发.
