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
      int n_replm_map;//
      errorCode =UF_MODL_replace_features(&first_element,1,&second_element,1,true,true,&replm_map,&n_replm_map);

函数注释：（小弟英文水平和理解力有限请大侠帮忙）
This function replaces the features in original_features[] by the
features in replacement_features[] or the copies of features in
replacement_features[] if original_features[] are features on bodies,
curve features and datum features. The children of the original_features[]
will be reparented to the replacement_features[] or copies.

The original features will be deleted.

original_features[] can contain: features on the same body, curve features,
datum plane and datum axis features.

replacement_features[] must contain: features on other bodies (if
original_features[] contains features on a body), other curve features
(if original_features[] contains curve features) and other datum plane
and other datum axis features (if original_features[] contains datum plane
or datum axis features).

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
is before the earliest feature in the original_features[].

parent_map[] maps entities created by the original_features[] to the
corresponding entities on the replacement_features[]. In addition to the
original_features[] and replacement_features[] you will have to provide a map
of edges and faces on the original_features[] to the corresponding edges and
faces of the replacement_features[].

You will specify the map as a array of objects of type
UF_MODL_replace_features_t described below. The children of the
original_features[] will be reparented to copies of the corresponding
entities on the replacement_features[] that are specified in the parent_map[].

Calling this function with return_map as true does not perform the replacement
but returns a parent_map[] each of whose original_entity elements are edges
and faces created by original_features[]. Only those edges and faces that are
parents of downstream features are returned in the parent_map[]. The
replacement_entity elements of all the structures in the parent_map[] are 0.
You will have to assign the appropriate replacement_entity for each of
the structures returned in the parent_map[] before calling this function with
return_map as false to perform the actual replace.
