【求助】UG 中如何实现对象的transform？

ddp_

比如要使UG中的一个实体进行旋转变换！
UG open API中说明使用：
  
uf5947_
  
Transform objects according to a previously defined matrix.
  
The upper limit on the number of objects to transform is 32767. The object types supported for non-uniform scaling are the same as those supported by non-uniform scaling in interactive Unigraphics.
  
函数原型如下：
extern void uf5947_ (
const double * rp1,  
const tag_t * np2,  
const int * ip3,  
const int * ip4,  
const int * ip5,  
const int * ip6,  
tag_t * nr7,  
tag_t * nr8,  
int * ir9 );
  
可是在使用此函数时返回值表明成功，但是实际没有完成；郁闷ing！！
  
程序代码如下：
