CAA: 如何取得external reference?

如果在一个PART中引用了另一个PART中的FEATURE, 如何在程序中获得它的原始对象?是用CATIMechanicalImport吗?怎么用呀?
  
谢谢各位!

我也遇到这个问题啊，等待各位高手的帮忙。谢谢。

怎么没人解答吗？

I found the solution:
  
first, you should go to Tools/Options/Infrastructure/PartInfrastructure, in Tab General, in the first block "external reference", select the first checkbox.
  
Code:
  
CATIPrtPart_var spPart(spSpecOnPart); // you get a part
CATListValCATISpecObject_var spBodies = spPart->GetImportedBodies();
int size = spBodies.Size();
CATUnicodeString extRefs;
for(int i=1; i<=size; i++)
{
  CATIMechanicalImport_var spImport(spBodies);
  CATISpecObject_var spOrig = spImport->GetSelectedFeatureInSourceProduct();
  CATIAlias_var spAlias(spOrig);
  CATUnicodeString strAlias = spAlias->GetAlias();
  
  extRefs += strAlias + ", ";
}
  
With CATIPrtPart::GetImportedBodies() you get the body refernces in the same part, and with CATIMechanicalImport::GetSelectedFeatureInSourceProduct() you get the original ones.
  
Does anybody know, how I can get the mapping of a feature and the external reference, which this feature is using (in the same part)? I mean, I have many features and many external references in a part, how can I find out, which feature uses which external reference? Any idea?
Thank you!

可以参考　powercopy
建议而已，对不对不知道

很遗憾地告诉你
CATIMechanicalImport在V5R15GA里出问题了，DS说给个代替的interface,但要等到sp2

和powercopy应该不同
  
powercopy是靠feature的CATIAttrBehavior的GetRequestedBehavior()来实现
  
返回的CATBehaviorSpecs的内容只能是同个part里的spec, 参照的linker也可以的
如果你这这时候用鼠标点了其他part的东西，powercopy命令的FeatureImportAgent会替你做个external reference,然后把它做为输入

一个一个找的方法比较笨，但肯定可以实现
CATISpecObject->CATISpecAttribute->找里面所有以tk_specobject的特性，然后把它变为CATBaseUnknown，再和external reference比较是不是一样
  
用PathElement或许也可以找到
  
或许有更好的方法，但在公开的interface好像没注意到过有相关的

非常感谢你的回答.
  
还有一个问题:  CATISpecObject 的Attribute有何作用?如果我改变tk_specobject的特性,是不是这个CATISpecObject就指向另一个external reference?
我实际上想用程序实现"替代"的功能,就象右击鼠标后出现的Context Menu 里的那个Replace.
不知道CATIReplace是否能实现这个功能,或者它只是改变CATISpecObjec特性而已?

Replace的filter是通过CATIAttrBehavior来实现的，
  
CATIReplace的Imp具体有什么用不太明了，按照ds的推荐，GSD的featuer不必自己写,solid的feature要。可以我做过的几个solid的feature好像自己不写也可以，或许默认的CATSpecReplaceExt::Replace(iNameOfRole,ispNewElement,ispOldValue)就够了
  
这2个都是feature的extension imp,所以如果你不自己做catalog建feature了话，一般不会接触到他们
  
自己写想万能的Replace？就用CATIAttrBehavior来取filter好了。举个例子，Pad应该有Skech的tk_specobject，但如果你给它换个CATCkeParm，结果可想而知。所以必须用filter做限制
