   function DrawSpline() {
              mxOcx.Cal("Mx_ShowWeight");
              var param = mxOcx.NewResbuf();
              mxOcx.SendStringToExecuteFun("_DrawSpline", param);
              var retparam = mxOcx.GetEntitysLastCmd();
              if (retparam == null)
                  return;
  
              if (retparam.Count == 0)
                  return;
  
              var spline = retparam.AtObject(0);
              if (spline == null) {
                  return;
              }
  
              spline.Lineweight = 20;
  
  
  
          }
