【求助】请看源程序！

我是想求出实体的体积，程序如下：
tag_t  view;
/*
其他参数的定义
*/
char zhp[20];
  UF_UI_selection_options_t opts;
  UF_UI_mask_t mask = {UF_solid_type, 0, UF_UI_SEL_FEATURE_BODY};
  int  response = 2;
  int type = 1;
  int  unit = 3;
  int accuracy =  1;
  int  count = 0;
  int  zero = 0;
  double  acc_val[11] = {.01,0,0,0,0,0,0,0,0,0,0};
  double  density = 1.0;
  double  massprop[47];
  double  massprop_stat[13];
  opts.num_mask_triples = 1;
  opts.mask_triples = [$mask]
  opts.scope = UF_UI_SEL_SCOPE_WORK_PART;
     if ( UF_initialize() != 0)  
          return ( UF_UI_CB_CONTINUE_DIALOG );
  
  UF_UI_select_with_single_dialog (
cue,  
title,  
UF_UI_SEL_SCOPE_WORK_PART,  
NULL,  
NULL,   
&response,  
&object,  
cursor,  
&view )；
uc1601("zhp",1);
  UF_CALL(UF_MODL_ask_mass_props_3d(view,///应该是在这里出错了
                                       count,
                                       type,
                                       unit,
                                       density,
                                       accuracy,
                                       acc_val,
                                       massprop,
                                       massprop_stat));
  sprintf(zhp,"%f",massprop[1]);
  uc1601(zhp,1);
  但是求得的数值好大，不对。我感觉应该是在view参数这里出错。我必须要用上边的 UF_UI_select_with_single_dialog 这个函数。怎么解决，请各位高手指点，多谢！！
