[OBMCE C#] 如何获取OBM元素对应的实体元素？

您好：可以先获取当前激活的Bridge对象，然后根据获取的Bridge对象获取BridgeUnit对象。然后通过BridgeUnit可以获取桥梁各个组件对象的相关信息。

    // Get current DgnModel
    DgnModelRef model = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnModelRef();
    
    // Create SDK connection
    SdkConnection con = SdkConnection.Create(model);
    
    // Get bridge model from SDK connection
    BridgeModel bridgeModel = con.BridgeModel;
    
    // Get active bridge from BridgeModel
    Bridge bridge = bridgeModel.ActiveBridge;
    
    if (null == bridge)
        {
        m_displayHelper.AddLine("No Active Bridge was found.");
        }
    else
        {
            foreach (var bridgeUnit in bridge.bridgeUnits)
            {
             // we can use bridgeUnit object to get what you want components object of the bridge.
             // ...
            }
        }

你好，谢谢回复，我注意到这样获取到的元素一个是OBM定义的扩展元素，我想获取的是这个元素对应的实体元素，比如一个布跨线可能是ExtendElementElement,我想获取这个ExtendElementElement对应的LineElement
