请再描述的详细些。

我在零件中建立了一个草图。里面只画了一个矩形框。我现在希望写个程序得到里面4条线的TAG。我在之前的程序中已经能得到草图的TAG。但是用UF_OBJ_cycle_in part和UF_SKET_ask_sketch_features扫描草图得到的都是NULL_TAG。请问这个程序应该怎么写呢？谢谢。谢谢。在线等。急啊。。。
4 C( j) A7 i, u9 J5 Z另外。UF_FEATURE_TYPE具体包括哪些类型呢？请问在哪儿能查到？

以下是我写的代码。从扫描零件开始。直到读取草图内容。刚开始学习UG。程序难免繁琐混乱。望大家见谅。尽力帮帮小弟。

不知道LZ是怎么解决的啊,
3 {1 d( f7 e8 ^+ @1 R; n. T
遍历完了得到的是整个 part 文件里的 tag ,如何区分出草图里的 tag呢


我现在只想用下草图里的 特征标识做下拉伸,

3 K, {; y3 }& X求教...

UF_OBJ_cycle_objs_in_part( main_body_tag, type, &sketch_line );  
" M! H* o# _* d- W, n& d
UF_OBJ_cycle_objs_in_part()第一个参数不用非得是 .prt文件的 tag吗,可以用草图的tag吗?
