"Structural" property for built-in parameter

[Anonymous]

For the attached image,

I have to enable "Structural" property for built-in parameter  using get_Parameter("").Set(1). Kindly let me know built-in Parameter name?

 Element e;
                        Floor F = e as Floor;
                        Parameter P = F.get_Parameter(BuiltInParameter.FLOOR_PARAM_IS_STRUCTURAL);
                        if(P!=null)
                        {
                            P.Set(1);                            
                        }

Hi Naveen,

I have tested now and FLOOR_PARAM_IS_STRUCTURAL is returning NULL. Its not working.

Hi @Anonymous,

Are you trying to set Structural property for Floor?

From your attached file,I assumed  that you are trying to set structural property for floor.

If you are trying to set structural property for Floor it should work because I tested it and it works fine for me.

Could you please provide any other information for further analysis?

Thanks,

Here is my code. Kindly review.
FilteredElementCollector collector = new FilteredElementCollector(doc);
IList foundations = collector.OfCategory(BuiltInCategory.OST_StructuralFoundation).WhereElementIsNotElementType().ToElements();
using (Transaction t = new Transaction(doc, "Bind Param"))
{
t.Start();
foreach (Element ifloor in foundations)
{
FamilyInstance gfloor = ifloor as FamilyInstance;
if (gfloor != null)
{
Parameter P = gfloor.get_Parameter(BuiltInParameter.FLOOR_PARAM_IS_STRUCTURAL);
if (P != null)
{
if (!gfloor.get_Parameter(BuiltInParameter.FLOOR_PARAM_IS_STRUCTURAL).IsReadOnly)
gfloor.get_Parameter(BuiltInParameter.FLOOR_PARAM_IS_STRUCTURAL).Set(1);
}

Parameter iParam = gfloor.get_Parameter(BuiltInParameter.STRUCTURAL_ANALYTICAL_MODEL);
if (iParam != null)
{
if (!gfloor.get_Parameter(BuiltInParameter.STRUCTURAL_ANALYTICAL_MODEL).IsReadOnly)
gfloor.get_Parameter(BuiltInParameter.STRUCTURAL_ANALYTICAL_MODEL).Set(1);
}
}
}
t.Commit();
}
