用VB读取dxf中数据.如果你不是专业开发CAD系统软件的，建议不要费这种功夫，除非有其它特殊考虑。CAXA、PKPM等软件为了方便用户，都备有多种与ACAD的交互接口包括DWG、DXF等。但自己搞这种工作，意义不大。因为如果你想在自己的应用程序中绘图并想在ACAD中编辑、查看，完全可用DXF格式，该格式内容公开，便于应用，VB生成也很快。ACAD打开该类文件也很快现在的电脑配置早已今非昔比，原来搞DWG的主要目的是想充分利用DWG格式高度紧凑而生成的文件小、从而易电脑操作的优点，但现在已没有这个必要了。 -VB dxf read data. If you are not in the development of professional CAD software, not recommended charges such efforts, unless there are other special considerations. CAXA, PKPM software for the convenience of users, are available with a variety of interactive interface ACAD including DWG, DXF, etc.. But their practice of this kind of work, little significance. If you wish to own application process mapping and would like to ACAD Edit, View, fully available DXF format, which as an open, easy to use, VB generation soon. ACAD open such documents will soon present configuration, which has been completely transformed. engage in the original DWG the main purpose is to make full use of highly compact DWG format documents generated small, so easy computer operation advantages, but there was no ne 下载
