UF_SF_find_minimum_distance

ccx8301

UF_SF_find_minimum_distance这个函数怎么用啊？有没有例子。
7 g0 R2 R& D6 z我创建了两个正方体，来求两个实体的最小距离，好像不行，且我已经把，feature转换成body的tag了。代码如下：
  int ret;
' q( n8 N2 y# {! f, i: X  tag_t body_tag_1;
/ _5 b9 L6 J/ ]2 s! Q& s  tag_t body_tag_2;
  tag_t cyl_tag;
7 [' ]+ q' l/ q" }' b  u# L* b  char *edge_lens[3]={"10","10","10"};
   ret=UF_MODL_create_block1(UF_UNITE ,origin,edge_lens,&cyl_tag);
4 g. |5 V' ^0 n8 x# Q) K( `- w  tag_t part_1;
% s" Q( H$ F7 |( K  double origin1[3]={0,0,20};
  char h1[256]="20";
  char d1[256]="40";

  ret=UF_MODL_create_block1(UF_UNITE ,origin1,edge_lens,&part_1);
6 ]5 `  r1 T1 Z( M' lUF_MODL_ask_feat_body(cyl_tag,&body_tag_1);
UF_MODL_ask_feat_body(part_1,&body_tag_2);
  double point[3],point1[3];
4 G5 a8 I2 k8 P  data.value.real=3.14;
  double min_dist;
   UF_SF_find_minimum_distance(body_tag_1,body_tag_2,&min_dist,point,point1);
  data.value.real=min_dist;
" @+ P9 w0 f$ ?  x   UF_STYLER_set_value(dialog_id,&data);
+ E& N( f& A8 P; B, s. m# ]0 p谢谢！！！！
