那位高手帮我看一下求实体体积的代码~~!

shaoxjin

我用 UF_UI_select_with_class_dialog()和 UF_MODL_ask_mass_props_3d()来得到零件体积，能够零件进行交互选择，但是老实得不到体积值~~！
int rcode = UF_UI_lock_ug_access(UF_UI_FROM_CUSTOM);
  if(rcode != UF_UI_LOCK_SET)
  {
    AfxMessageBox("failed to lock");
    return;
  }
  
  char *message = "请选择实体";
  char *title = "选择实体";
  int response,sel_count;
  tag_p_t sel_objects;
  int ret = UF_UI_select_with_class_dialog(message,title,UF_UI_SEL_SCOPE_NO_CHANGE,
    NULL,NULL,[$response,&sel_count,&sel_objects)]
  
  if(ret == 0)
  {
    if(response == UF_UI_OK && sel_count>0)
    {
      objects = sel_objects;
      count = sel_count;
    }
  }
  else
    AfxMessageBox("ret != 0");
  
  rcode = UF_UI_unlock_ug_access(UF_UI_FROM_CUSTOM);
  if(rcode != UF_UI_UNLOCK_SET)
    AfxMessageBox("failed to unlock");
  
//计算体积
      int type = 1;//solid body
    int units = 1;
    double density = 1;
    int accuracy = 1;// Use Accuracy
    double acc_value[11] = {1.0,0,0,0,0,0,0,0,0,0,0};
    double  mass_props[47];//output
    double  statistics[13];//output
  
    int retn = UF_MODL_ask_mass_props_3d(objects,count,type,units,density,
      accuracy,acc_value,mass_props,statistics);
  
    if(retn == 0)
    {
      CString volume;
      CString test;
      volume.Format("%f",mass_props[1]);
      test = volume;
      AfxMessageBox("test~!");
      
      SetDlgItemText(IDC_VOLUMEEDIT, volume);
    }
    else
      AfxMessageBox("计算体积错误！");
