飞狐，能不能用VB。NET写一下！

雪山飞狐_lzh

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

可以把dll传上来吗?硬盘太小,没有装C#

   if(mPromptCounter == 0)
   {
    jigOpts.Message = "\n请输入基点:";
    romptPointResult dres = prompts.AcquirePoint(jigOpts);
     
    oint3d positionTemp = dres.Value;
    if(positionTemp != mPosition)
    {
     mPosition = positionTemp;
    }
    else
     return SamplerStatus.NoChange;

    if(dres.Status == PromptStatus.Cancel)
     return SamplerStatus.Cancel;

感觉AcquireAngle好像取的是距离，难道是个BUG？

在autocad2006下不能运行

sailor538

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
