How to connect conduit with fittings?

[Anonymous]

Hello!
I have created conduit element between the box and the conduit elbow, but I had a problem with conduit connection - by default it is not connected with elbow fitting

I know about connector1.ConnectTo(connector2) method, but there is the problem with obtaining connectors from my conduit. How can I make connection between elbow and conduit with API?

//GETTING CONNECTORS FROM ELBOWS
IList<Connector> connectors = new List<Connector>();
foreach (Element elb in elbows)
{
   if ((elb as FamilyInstance).MEPModel.ConnectorManager != null)
   {
       foreach (Connector con in (elb as 
            FamilyInstance).MEPModel.ConnectorManager.
            Connectors.Cast<Connector>())
       {
           connectors.Add(con);
       }
    }
}

//CREATE CONDUITS
//points.OrderByDescending(x => x.X).Last() - intersection point with box
//curve.GetEndPoint(0) - start point (equals to elbow's connector origin)
Conduit first = Conduit.Create(doc, type, curve.GetEndPoint(0), 
   points.OrderByDescending(x => x.X).Last(), conduit.LevelId);

//TRYING TO MAKE CONNECTION
foreach (Connector c in connectors)
{
    if (c.Origin.IsAlmostEqualTo((first.Location as 
        LocationCurve).Curve.GetEndPoint(0)))
    {
        //CONNECTOR'S ORIGIN EQUALS TO CONDUIT'S CURVE START
    }
    else if (c.Origin.IsAlmostEqualTo((first.Location as 
        LocationCurve).Curve.GetEndPoint(1)))
    {
        //CONNECTOR'S ORIGIN EQUALS TO CONDUIT'S CURVE END
    }
}

What is the problem you encounter? Your description, drawing and code all look more or less OK. There seem to be some parts missing from the code, though, so it is hard for to see exactly how the bits and pieces should work together.

In manual creation I can create conduit between elbows, then I press 'Tab' button and we can see that neighbouring elbows are highlighted too (conduit connected to the fittings):

but if I try to press 'Tab' after programmatic creation, nothing will happen, the neighbouring elbows are not highlighted with the conduit:

I just get conduit that disconnected from fittings.

Is there any way to fix this moment using Revit API?
