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？

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
% E+ n- W# L9 R0 t- {( p- qfeatures in replacement_features[] or the copies of features in
replacement_features[] if original_features[] are features on bodies,
2 V! N$ Z% _5 _, u4 Fcurve features and datum features. The children of the original_features[]
/ Q- }7 e3 l! U) z; K+ Dwill be reparented to the replacement_features[] or copies.
- M& i9 f( U* H1 Q
The original features will be deleted.
4 ^: [# \6 C' ^/ S2 ]- h" `$ ]
original_features[] can contain: features on the same body, curve features,
datum plane and datum axis features.

7 V) y# _2 M$ l* Qreplacement_features[] must contain: features on other bodies (if
/ S9 H5 X7 b! N1 C8 _original_features[] contains features on a body), other curve features
(if original_features[] contains curve features) and other datum plane
, O$ e3 g" C. B1 z( c) Oand other datum axis features (if original_features[] contains datum plane
or datum axis features).
6 z/ g) t- y4 Q- e
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[].
& n. v, x* o1 I8 o8 C0 b
parent_map[] maps entities created by the original_features[] to the
' p) \- o- v4 B4 ccorresponding entities on the replacement_features[]. In addition to the
original_features[] and replacement_features[] you will have to provide a map
0 H9 m% V' @2 q7 U1 `7 U: sof edges and faces on the original_features[] to the corresponding edges and
$ k1 M0 ~( O3 d! K4 Cfaces 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
6 x. r% {5 F0 M, [) koriginal_features[] will be reparented to copies of the corresponding
  V/ n* J& D- a- \+ l6 m: zentities on the replacement_features[] that are specified in the parent_map[].

and faces created by original_features[]. Only those edges and faces that are
parents of downstream features are returned in the parent_map[]. The
9 {6 q0 {* X0 B! greplacement_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
% a+ [' t4 \9 y5 dreturn_map as false to perform the actual replace.
