Revit 二次开发之“在机械设备之间创建机械系统”

创建了机械系统，没有用风管连接起来。还不太理解，记录一下。

ConnectorSet connectorSet = new ConnectorSet();
Connector baseConnector = null;
ConnectorSetIterator csi = null;
ElementSet selection = sel.Elements;
foreach (Element e in selection)
{
    if (e is FamilyInstance)
    {
        FamilyInstance fi = e as FamilyInstance;
        Family family = fi.Symbol.Family;
        if (family.FamilyCategory.Name == "机械设备")
        {
            if (null != fi.MEPModel)
            {
                csi = fi.MEPModel.ConnectorManager.Connectors.ForwardIterator();
                while (csi.MoveNext())
                {
                    Connector conn = csi.Current as Connector;
                    if (conn.Direction == FlowDirectionType.Out && conn.DuctSystemType == DuctSystemType.SupplyAir)
                    {
                        baseConnector = conn;
                        break;
                    }
                }
            }
        }
        else if (family.FamilyCategory.Name == "风道末端")
        {
            csi = fi.MEPModel.ConnectorManager.Connectors.ForwardIterator();
            csi.MoveNext();
            connectorSet.Insert(csi.Current as Connector);
        }
    }
}
MechanicalSystem mechanicalSys = null;
PipingSystem pipingSystem = null;
if (null != baseConnector && connectorSet.Size > 0)
{
    mechanicalSys = doc.Create.NewMechanicalSystem(baseConnector, connectorSet, DuctSystemType.SupplyAir);
    //pipingSystem = doc.Create.NewPipingSystem(baseConnector, connectorSet, PipeSystemType.SupplyHydronic);
}
