如题，请问如何获取MS里面一个立方体的拓扑结构信息？
我再MS CE版本的开发文档里面看到，关于实体元素，ISolidKernelEntity represents a boundary representation body (BRep).
如下：
我想请问，如何获取拓扑关系？“”The topology is the faces, edges, and vertices that describe how the geometry is connected.“”
我试过
并没有找到哪里有拓扑关系的描述？
求指教~谢谢~~~
你在MS SDK目录下的PSolidCoreAPI.h中的struct TopologyID结构体，可以找到相关信息。
感谢，找到了一些拓扑信息；
请问有没有样例代码供参考？我之前没有写过Solid相关的代码。在SDK的example中没有找到TopologyID相关的内容。
谢谢~~
Work smart， not just work hard！

UInt32 lowestNodeId;
BentleyStatus status = SolidUtil::TopologyID::FindNodeIdRange(*srcSolid, highestNodeId, lowestNodeId);
if (SUCCESS == status)
{

mdlDialog_dmsgsPrint(wStr.GetWCharCP());
}
UInt32 nodeId = 33;
bool overrideExisting = false;
status = SolidUtil::TopologyID::AddNodeIdAttributes(*srcSolid, nodeId, overrideExisting);

老师，您举的几个例子都是使用ISolidKernelEntityR 类的。
我想测试一下IdFromFace (FaceId &faceId, ISubEntityCR subEntity, bool useHighestId)等几个用ISubEntityCR的方法。。。。
ISolidKernelEntityR到ISubEntityCR怎么转换？或者EditElementHandle到ISubEntityCR怎么转换？
