How to change sub-discipline value by code

Anonymous — Thu, 16 Aug 2018 17:36:37 GMT

Hi,

how can I change the value of the "Sub-discipline" property , I found how can I validate it like this :

string strDiscipline = doc.ActiveView.LookupParameter("Sub-Discipline").AsString();

and a routine:

BindingMap map = doc.ParameterBindings;
DefinitionBindingMapIterator it = map.ForwardIterator();

it.Reset();
StringBuilder st = new StringBuilder();
Element projectInfoElement = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_ProjectInformation).FirstElement();

while (it.MoveNext())
{
    if (it.Key.Name == "Sub-Discipline") {
          ElementBinding element = it.Current as ElementBinding;
          Parameter foundParameter= projectInfoElement.get_Parameter(it.Key);
}

but return null when fund the propierty,

How can I get the current array of sub-disciplines, and pick one to change it?

Regards!!

Hi, I found this way to change the sub-discipline in the activeview after a couple of weeks trying, hope this can help to other novate programmers in Revit.

P.S. I don't know if this is the good practice to do it, but It's the way that works for me.

 if (!string.IsNullOrEmpty(doc.ActiveView.LookupParameter("Sub-Discipline").AsString()))
     doc.ActiveView.LookupParameter("Sub-Discipline").Set("MY_EXISTING_SUB-DISCIPLINE");

Regards!
