第一个支持。研究研究。

飞狐，能不能用VB。NET写一下！

雪山飞狐_lzh 发表于 2005-7-18 12:36:00

把代码编译为Dll后，可以在VB.Net里引用的，用VB.Net写一下就比较头痛了：）

月海临风 发表于 2005-7-18 19:08:00

可以把dll传上来吗?硬盘太小,没有装C#

雪山飞狐_lzh 发表于 2005-7-20 12:11:00

我把这里改过了，想输入角度，直接输入值没问题，但鼠标动作时有问题，郁闷

感觉AcquireAngle好像取的是距离，难道是个BUG？

在autocad2006下不能运行

sailor538 发表于 2007-7-17 19:29:00

代码中还是有几处问题,修改后成功了,但有些问题很困惑1.用F8运行,为什么出现问题 ,要求输入点的地方不停顿,F5就行2.把块删掉后 PURGE 重建一个，就不能正确运行了，是什么原因lzh741206版主能加我QQ:79850399

AutoCadTM说缺少using指令集或程序集引用怎么回事！
我是新手请大家多多指导！
