该函数的用法UF_MODL_replace_features                                                                                                                                                                                                                                                                                                                        问题描述：
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
; x2 @/ Y" ?; k# F% E, T7 a( [        int n_replm_map;//
: q3 @/ ]2 h  q& T* B# \- l        errorCode =UF_MODL_replace_features(&first_element,1,&second_element,1,true,true,&replm_map,&n_replm_map);
* N) O9 k2 R/ z! h" F1 w# g. }

another feature in the replacement_features[] or must be a feature which
is before the earliest feature in the original_features[].
