自动装配简单的例子

wanxin9999

嗯，五一劳动节，劳动了7天，比较光荣的完成了一点活。
我的娱乐项目就是在坛子里淘帖子了。
发现有很多同仁在在这里问道关于自动装配的问题。
我的课题在探索方法之初，我也做了一个很简单的例子。
拿出来献丑了，这都是难者不会，会者不难的东西吧。
希望给有疑问的一点有些启发，高手就不要笑话我了。
  
例子是做两个圆柱自动装配的例子。
先贴一下代码。
  
//打开第一个零件：
int CHANGE_add1_0_act_cb ( int dialog_id,
             void * client_data,
             UF_STYLER_item_value_type_p_t callback_data)
{
  char * part1="D:\\ugexam\\ugexam\\a.prt";
  char * refset_name1=NULL;
  double origin1[ 3 ]={0.0,0.0,0.0};
  char * instance_name1="a";
  double csys_matrix1[ 6 ]={1.0,0.0,0.0,0.0,1.0,0.0};
  
  int layer1=0;
  tag_t   instance1;
  int ret;
  char message[133];
  UF_PART_load_status_t error_status1;
  
  /* Make sure User Function is available. */   
  if ( UF_initialize() != 0)  
    return ( UF_UI_CB_CONTINUE_DIALOG );
  /* ---- Enter your callback code here ----- */
  //创建一个新的文件,再里面逐个增加零件,在产生配合条件进行装配
  //UF_UI_open_listing_window();
  
  UF_CALL(UF_PART_new(part_name1, UF_PART_ENGLISH, [$part))]  
  ret = UF_ASSEM_add_part_to_assembly (part, part1, refset_name1, instance_name1, origin1,
    csys_matrix1, layer1, [$instance1, &error_status1 )]
  if(ret != 0)
  {
    UF_get_fail_message(ret,message);
  }
  
  
  UF_terminate ();
  
    /* Callback acknowledged, do not terminate dialog */
    return (UF_UI_CB_CONTINUE_DIALOG);  
    
    /* or Callback acknowledged, terminate dialog.    */
    /* return ( UF_UI_CB_EXIT_DIALOG );               */
  
}
  
//在第一个零件中加入第二个零件。
int CHANGE_add2_1_act_cb ( int dialog_id,
             void * client_data,
             UF_STYLER_item_value_type_p_t callback_data)
{
  char * part2="D:\\ugexam\\ugexam\\b.prt";
  char * refset_name2=NULL;
  double origin2[ 3 ]={0.0,0.0,0.0};
  char * instance_name2="b";
  double csys_matrix2[ 6 ]={1.0,0.0,0.0,0.0,0.0,1.0};
  
  int layer2=0;
  tag_t   instance2;
  UF_PART_load_status_t error_status2;  
  
  /* Make sure User Function is available. */   
  if ( UF_initialize() != 0)  
    return ( UF_UI_CB_CONTINUE_DIALOG );
  
  /* ---- Enter your callback code here ----- */
  
  UF_CALL(UF_ASSEM_add_part_to_assembly (part, part2, refset_name2, instance_name2, origin2,
    csys_matrix2, layer2, [$instance2, &error_status2 ))]
  
  
     UF_terminate ();
  
    /* Callback acknowledged, do not terminate dialog */
    return (UF_UI_CB_CONTINUE_DIALOG);  
    
    /* or Callback acknowledged, terminate dialog.    */
    /* return ( UF_UI_CB_EXIT_DIALOG );               */
  
}

嗯，很早以前做的例子，很久没试了。
发帖有点不大灵光，先发了。有问题及时告诉一声，我会赶紧改的。
