当然可以

不好意思,我这个二次开发这东西从来没有搞过,所以不懂~

不知道怎么使用

woaishuijia · 发表于 2008-7-30 15:05:02

1、确认你的ACAD安装了VBA支持；
2、由于页面上的代码与表情有混淆，下载5楼附件，解压后是一个文本文件，打开它，全部选择，复制；
3、运行CAD，“Alt+F11”打开“VBA编辑器”；
4、双击“工程资源管理器”中的“Thisdrawing”对象，显示代码窗口，在其上粘贴。
5、保存，便于以后使用；
6、回到CAD界面，“Alt+F8”，对话框中有两个程序，任选一个“运行”，按命令行提示操作。两个程序的异同点请自已尝试。

以后再次使用：
1、“appload”命令，在打开文件对话框中选择前面保存的dvb格式文件，加载；
2、“Alt+F8”，“运行”；或“-vbarun”命令，在提示输入宏名称时键入“lianx”或“uniteline”，回车。
