该函数的用法UF_MODL_replace_features                                                                                                                                                                                                                                                                                                                        问题描述：
1 B' f$ P. N8 O  Q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
6 `; C9 s$ \+ _" xfeatures in replacement_features[] or the copies of features in
9 P, Y8 e" b- V) greplacement_features[] if original_features[] are features on bodies,
4 a3 J+ h$ z% j5 B5 ycurve features and datum features. The children of the original_features[]
will be reparented to the replacement_features[] or copies.
, C3 z, @: S& w0 D; W- J
The original features will be deleted.
( E" D/ l, v; x7 j+ m0 X
original_features[] can contain: features on the same body, curve features,
8 U& a9 z: V3 J$ Hdatum plane and datum axis features.
- D- _3 K. V) Z# C0 ?7 {
$ q/ c- ~  _. G% Nreplacement_features[] must contain: features on other bodies (if
7 D) s- s$ @8 f4 v% S% q/ r" H+ coriginal_features[] contains features on a body), other curve features
(if original_features[] contains curve features) and other datum plane
3 a* z5 Q2 K, L! l  ?and other datum axis features (if original_features[] contains datum plane
or datum axis features).

Note that original_features[] and replacement_features[] must contain
/ j) I4 N; e* O7 V3 K- h  Mfeatures 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
$ m7 I: Q1 Q. c: Oanother feature in the replacement_features[] or must be a feature which
# H6 W" p4 \/ b. O, z! Eis 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
" Q# \5 M4 H( s3 B4 H0 Loriginal_features[] and replacement_features[] you will have to provide a map
0 h  c* M0 T5 A- J" Xof edges and faces on the original_features[] to the corresponding edges and
5 {/ C; l  d$ ufaces 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
% L1 }& z. y. `2 O  I5 n8 f0 Woriginal_features[] will be reparented to copies of the corresponding
* U% R) k1 q. O# M) xentities on the replacement_features[] that are specified in the parent_map[].

/ K6 M5 r) |+ |Calling this function with return_map as true does not perform the replacement
( c' G! e/ z; j4 mbut returns a parent_map[] each of whose original_entity elements are edges
! a, q; H: U( d4 Pand faces created by original_features[]. Only those edges and faces that are
parents of downstream features are returned in the parent_map[]. The
' J7 v! e: T% \' G) W& @5 Xreplacement_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.
