Collect Room Tag Families

rvtquestions — Mon, 26 Mar 2018 13:50:06 GMT

Community,

I am trying to collect all parent family types of a Room Tag within a project. Before I continue, I would like to preface by saying that:

- I have experience with the API and Filtered Element Collector, however, having a little road bump with this one

- I have read through examples like collecting OST titleblocks which was a similar situation

The main line of code in question is this:

ICollection<Element> tagtypes = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_RoomTags).OfClass(typeof(Family)).ToElements();

When I iterate over each element in tagtypes to get its .Name it returns nothing

ICollection<Element> tagtypes = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_RoomTags).ToElements();

When I iterate over each element in tagtypes to get its .Name it returns each room tag's respective Family Type Name

What I would like is the Name of each PARENT Room Tag Family. So if a project had (5) Room Tag Families. Regardless of subsidiary Types, I would like just a list of the names of those (5) Room Tag Families. Is there something I need to adjust with my collector statement? Thank you!

families are a bit quirky. You find the Category via family.FamilyCategory instead of the usual family.Category.

			IEnumerable<Element> roomtagFamilies = new FilteredElementCollector(doc)
				.OfClass(typeof(Family))
				.Cast<Family>()
				.Where( f=> f.FamilyCategory.Id.IntegerValue == (int)BuiltInCategory.OST_RoomTags);
