该函数的用法UF_MODL_replace_features                                                                                                                                                                                                                                                                                                                        问题描述：
5 W9 C  H+ Y" h) Q7 Z+ E7 G& X% G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？

This function replaces the features in original_features[] by the

curve features and datum features. The children of the original_features[]
will be reparented to the replacement_features[] or copies.
