Get Boundary Elements in RVT 16

[rvtquestions]

I am trying to test out and learn more about the room/space and boundary classes for the Revit API. I tried debugging an example I found from Jeremy:

Under the section: 

GetBoundarySegmentElement External Command Implementation

http://thebuildingcoder.typepad.com/blog/2013/10/determining-a-room-boundary-segment-generating-elem...

However debugging gives me the error:

---

List<Room> rooms = new List<Room>(
sel.Elements.Cast<Room>() );

Error CS1061 'Selection' does not contain a definition for 'Elements' and no extension method 'Elements' accepting a first argument of type 'Selection' could be found (are you missing a using directive or an assembly reference?) GetBoundarySegmentElement 

---

foreach( BoundarySegment seg in loop )
{
Element e = seg.Element;

Severity Code Description Project File Line Suppression State
Warning CS0618 'BoundarySegment.Element' is obsolete: 'This property is deprecated in Revit 2016. Use ElementId instead.' GetBoundarySegmentElement

Any help would be greatly appreciated to help get this running for RVT 16. Thank you!

You need to migrate the code to the new API.

That is trivial.

First time migration, including some reading of 'What's New' information: 20 minutes, maybe.

Next time: less than five minutes.

 Have you searched for an answer at all?

I must have answered this dozens of time already.

Surely some trace must remain somewhere?
