Access element in a loaded family

EDIT:

I just realized this is posted in the wrong section "Trouble Shooting".  I am not sure how to move this to the correct forum section 'General' other than re-post.

Hi all,

How can enter a loaded family and access elements in this loaded family?  Specifically a filled region that is placed in a Title Block, I want to return this filled region's bounding box.

I have tried 'GetSubComponentIds()' and 'GetSubelements()' but both return '0'.

Any guidance would be greatly appreciated.

Thanks

AlanC.

are you trying to use Dynamo? Dynamo has there own Forum.

no, I am using C#

the snip-it you show, I can see the confusion, my mistake.

what I am doing is returning a count of sub elements, just to see if I can access them, here is the code I used

TD() is shortcut function for TaskDialog.Show("task", e.GetSubelements().Count.ToString());

When I select my title border with the code below, the result is '0' but  this border is full of stuff.

Reading this, https://thebuildingcoder.typepad.com/blog/2010/02/nested-family-instance.html

Maybe I need to use 'GetSubComponentIds()' and 'SuperComponent' but I still got '0' when replacing 'GetSubelements' with 'GetSubComponentIds().  I am assuming that SuperComponent is the parent family, the definition is not clear.

ISelectionFilter filter = new myFunctions.mySelectionFilter();
            Reference reference = uidoc.Selection.PickObject(ObjectType.Element, filter);

            FamilyInstance e = (FamilyInstance)doc.GetElement(reference);
            TD(e.GetSubelements().Count.ToString());

So I assume I posted in the Revit Trouble shooting forum...  I will repost, in the proper place.

Thanks

It would be better, if you ask your question here.
