NX二次开发-获取面的外围边和孔槽边

函数：

UF_MODL_ask_face_loops()  获取面的所有封闭边组合（多组edge）

UF_MODL_ask_loop_list_count() 获取loop的数量（面上孔、槽的数量+1）

UF_MODL_ask_loop_list_item() 获取loop成员，和成员有三种：外围=1, 孔槽=2, 其他=3，第四个参数为edge链

UF_MODL_ask_list_count()获取边链中边的数量

UF_MODL_ask_list_item()获取边链的成员

函数说明：使用UF_MODL_ask_loop_list_item()获取面的外围边和孔槽边，如下图
