Could I get another FamilyInstance when using NewElbowFitting

tristaVXAM4 — Mon, 10 Nov 2025 05:36:30 GMT

Hello,

There are two pipes with different diameters.

When I use "NewElbowFitting" to create fitting, revit would create two fittings.

But the "familyInstance" means the elbow, not both of them.
familyInstance = doc.Create.NewElbowFitting(conn1, conn2);

How to get the familyInstance of the other fitting?

Thank you.

I think there is no built-in function, but you can go through the connectors of your tap and find the connected fitting of the transition through this.

try subscribing to a Document changed event, its should give you the elementids of both objects each time a newelbow is created.

private void OnElemCreation(object sender, DocumentChangedEventArgs e) { e.GetAddedElementIDs(); //should have all the element ids at time of creation {
