实体是在草图画好后拉伸的，不是程序生成的，现在要用程序把这个实体旋转一个角度，该怎么实现啊？我写的程序如下，但是运行后没有反应。编译没有问题的，求给为大神指点
tag_t displayed_part;
      displayed_part = UF_PART_ask_display_part();
      int type1;
      tag_t solid;
      type1 = UF_solid_type;
      solid = NULL_TAG;
  tag_t  tag_solid[4];
  char mess[133];
  int i=4;
  do
  {
UF_OBJ_cycle_objs_in_part(displayed_part,type1,&solid );
int type2,subtype,body_type;
UF_OBJ_ask_type_and_subtype(solid, &type2, &subtype);
if(subtype == UF_solid_body_subtype)
{
UF_MODL_ask_body_type (solid, &body_type);
if (body_type==UF_MODL_SOLID_BODY)
{
   tag_solid[i]=solid;
   sprintf(mess,"%d",tag_solid[i]);
   i++;
}

}
} while (solid != NULL_TAG);  //获取图中的部件
double origin[3]={0.0,0.0,0.0};
      double direction[3]={1.0,0.0,0.0};
  double degrees_rotation=45;
  double matrix[16];
  int status;
  FTN(uf5945)(origin,direction,&degrees_rotation,matrix,&status);
      int ip3=1;
  int ip4=1;
      int ip5=-1;
  int ip6=1;
  int ir9;
      tag_t nr7,nr8;
  const tag_t np2[1]={solid};
      FTN(uf5947)(matrix,&solid,&ip3, & ip4, &ip5, & ip6, &nr7, &nr8, &ir9);
