DXF在AutoCAD二次开发中的应用

Application of DXF in the Secondary Development of AutoCAD

由于AutoCAD数据库中,其存储方式是以其特有的格式DXF组码和组值来表示的,所以AutoCAD的二次开发接口需要利用DXF来实现。文章在分析了AutoCAD数据存取格式的基础上提出了DXF的AutoCAD的图形数据读取方法的原理和过程,并通过一个实例对上述方法进行验证。

As in the database of AutoCAD, its storage method is a unique format DXF group codes and group values, therefore, the secondary development interface of AutoCAD need to use DXF to implement. This article based on the analysis of the data access format of AutoCAD, make principles of reading methods and the process of AutoCAD graphics data of DXF. And through an example to verificate the above - mentioned methods.
