该函数的用法UF_MODL_replace_features                                                                                                                                                                                                                                                                                                                        问题描述：
" s6 r# ?  z/ |7 N% G6 ^现在画两条线，将其中一条拉伸成面，然后进行如下操作：用未拉伸的线去替换拉伸的线，并使得拉伸的面也移动到未拉伸的线出，也就是子特征也拷贝过去，我用上面的函数UF_MODL_replace_features操作发现拉伸特征并没有拷贝过去，单步调试发现返回值不为0，最后一个参数n_parent_map为巨大的负数，看了英文帮助发现有点难懂，遂请大侠帮忙看看如何实现我的功能单靠这个函数是否能实现，如果能我的参数设置是不是错误了，错在哪儿？
代码：
        UF_MODL_replace_features_t *replm_map=NULL;//帮助写可为输入/输出参数，我作为输入，不知道正确与否
9 D. I7 D/ {4 K- Q- Y) N        int n_replm_map;//
        errorCode =UF_MODL_replace_features(&first_element,1,&second_element,1,true,true,&replm_map,&n_replm_map);

Note that original_features[] and replacement_features[] must contain
features that are in the same part file. Also, for features on a body, the
parents of each of the features in replacement_features[] must be either
another feature in the replacement_features[] or must be a feature which
