Problem with automatic connection of Pipe and Pipe Accessory in C#

[Anonymous]

Hello.

I created a Pipe and created a Pipe Accessory programmatically. (Image right)

And I used the ConnectTo function, but my Pipe Accessory did not change the size.

(Left of the image) Preferences are set, so I think it should be converted automatically when connecting in Revit.

But it doesn't work. Is this normal?

transaction.start();
var pipe = Pipe.Create(document, systemTypeId, pipeTypeId, levelId, startPoint, endPoint);
var pipeConnector = pipe.ConnectorManager.Connectors; //(summary) endpoint
transaction.commit();

transaction.start();
var familyInstance = document.Create.NewFamilyInstance(endPoint, symbol, level, structuralType);
var familyInstanceConnector = familyInstance.MEPModel.ConnectorManager.Connectors; //(summary) near endpoint
transaction.commit();

transaction.start();
pipeConnector.ConnectTo(familyInstanceConnector);
transaction.commit();

Thanks.
