protected override SamplerStatus Sampler(JigPrompts prompts)
      {
         JigPromptPointOptions jigOpts = new JigPromptPointOptions();
         jigOpts.UserInputControls =
            UserInputControls.Accept3dCoordinates |
            UserInputControls.NoZeroResponseAccepted |
            UserInputControls.NoNegativeResponseAccepted |
            UserInputControls.NullResponseAccepted;

         switch (m_Count)
         {
            case -1:
                  jigOpts.Message = "\n指定第一点:";
                  break;
            case 0:
            default:
                  jigOpts.Cursor = CursorType.RubberBand;
                  jigOpts.SetMessageAndKeywords("\n指定下一点或 [输入长度(m)]:", "4.5");
                  jigOpts.UseBasePoint = true;
                  jigOpts.BasePoint = m_StartPoint;
                  break;
         }

         PromptPointResult res = prompts.AcquirePoint(jigOpts);
         m_Status = PolyLineJigStatus.Add;
这个单位默认是毫米  我要怎么才能更改单位呢？比如改成米或者英寸？
