UG 虚拟自动装配问题，等待大侠啊

xuju1231

各位大侠，小弟在做UG虚拟自动装配。首先小弟将零件加载的新建的装配文件中，然后查找加载进来的零件的tag，然后填充装配约束，可装配的时候遇到问题，问题见下面的代码。望大侠不吝赐教啊，小弟感激不尽。我先加载一个零件通过UF_ASSEM_ask_parent_component得到to_part_occ,再加载第二个零件也通过这个函数得到from_part_occ，但得到的这两的tag值都是0，不知为何啊？？？？？？？肯定是这两个值为0才了装配不成功的。
求大侠赐教啊{:soso_e163:}{:soso_e163:}{:soso_e163:}{:soso_e163:}，问题解决后小弟定当感谢
