'Duct hanger - place family instance Revit API

i'm trying to place a family using the API (c#).

When using the NewFamiltInstace overloaded method that takes (location, symbol,host, level, structural) - i'm expecting to get the instance of the hanger family in the level i have inserted, and in the elevation of the host ( the duct).

instead - i get the duct hanger in the ground floor no matter what i'm doing, can any one understand why, and what sholud i do to get it in the desired level?

  • tried multiple overloaded methods, tried using the duct as a host, the level as a host etc.. the hangers always show up at the floor of ground level.

the code from my transaction: '''

using (Transaction trans = new Transaction(doc, "Place Family"))
{
trans.Start();


int indx = 0;
foreach (XYZ hanger_xyz in hangerCoordinates)
{

if (!hangerSymbol.IsActive)
{
hangerSymbol.Activate();
}

doc.Create.NewFamilyInstance(hanger_xyz, hangerSymbol,duct,level, Autodesk.Revit.DB.Structure.StructuralType.NonStructural);

}

trans.Commit();
}

'''
