Hi,

you can create a duct with two points (XYZ) :

public static Duct Create(
	Document document,
	ElementId systemTypeId,
	ElementId ductTypeId,
	ElementId levelId,
	XYZ startPoint,
	XYZ endPoint
)

Next, for fittings, you need to create them with the connectors of the ducts. Here is a exemple of how to find the connectors and create an elbow :

//create the ducts
Duct newduct = Duct.Create(doc, mepSystemId, ductTypeId, levelId, pt1, pt2);
Duct newduct2 = Duct.Create(doc, mepSystemId, ductTypeId, levelId, pt2, pt3);

//find the connectors at point 2 :
Connector connectorElbow1 = null;
Connector connectorElbow2 = null;
foreach (Connector connectduct in newduct.ConnectorManager.Connectors)
{
      if (connectduct.Origin.IsAlmostEqualTo(pt2))
      {
          connectorElbow1 = connectduct;
      }
}

foreach (Connector connectduct in newduct2.ConnectorManager.Connectors)
{
        if (connectduct.Origin.IsAlmostEqualTo(pt2))
        {
             connectorElbow2 = connectduct;
        }
}

//Create Elbow
FamilyInstance newElbow = doc.Create.NewElbowFitting(connectorElbow1, connectorElbow2);
