ug实体的复制和平移问题

最近小弟做毕业设计，刚接触ug二次开发，想实现实体的复制和平移，但是函数FTN(uf5947)的返回值resp＝3，不为0，不知应该怎样改正，请高手赐教，源代码如下

你检查一下
FTN(uf5943)(orig_iset,matrix );  
  
这里的输入，你用的是orig_iset应该是你要移动的一个向量
比如你要从orig_iset移动到新的一点a = {x,y,z};
那么应该定义length = {orig_iset[0] - x,orig_iset[1] - y,orig_iset[2] - z};
FTN(uf5943)(length,matrix );  
而你输入的这个是让你希望移动的物体移动y方向390吗
或者你查一下你的matrix的返回值是多少？

3 - Invalid Object (Not Alive Or Not
Transformable)
  
你创建的旋转特征，圆柱特征。。。那些tag是特征tag，而这个函数要求对象的tag。
