标题: 用UF_MODL_ask_mass_props_3d求体积的问题
用UF_MODL_ask_mass_props_3d求一个正方体（边长100）的体积时，返回值是61~~！

mass_props[1]是volume~~!

下面是代码：
  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 retn = UF_UI_select_with_class_dialog(message,title,UF_UI_SEL_SCOPE_NO_CHANGE,
   NULL,NULL,[$response,&sel_count,&sel_objects)]

   if(retn == 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 ret = UF_MODL_ask_mass_props_3d(objects,count,type,units,density,       
   accuracy,acc_value,mass_props,statistics);      
   if(ret == 0)     
   {       
   CString volume ;       
   volume.Format("%.1f",mass_props[1]);       
   SetDlgItemText(IDC_VOLUMEEDIT, volume);

   }     
   else       
   AfxMessageBox("计算体积错误！");

int units Input Units of mass and length
1 = Pounds and inches
2 = Pounds and feet
3 = Grams and centimeters
4 = Kilograms and meters
