Inside and outside room boundaries

- [Instructor] I was able to use Dynamo…to place wall protection families…around the outside boundaries of this room.…But what about a room where I would like to…place wall protection around the outside boundaries…as well as the inside boundaries?…I'm gonna click Change on the Select Model Elements node,…and select the Outside/Inside Boundaries room,…inside of the Revit project.…Now if I click Run inside of Dynamo,…you'll see that I've placed the wall protection family…around the outside edges of the room.…The custom node ProcessRoomBoundaries…processes the outside curves of the room,…as well as the inside curves.…

I'm gonna copy and select the elements…inside of this workspace, and use them…for the inside boundaries instead of just the outside.…I'm gonna cross-select…all the nodes inside of the workspace,…and hold Ctrl on my keyboard, and click and drag…to copy them down below inside of the workspace.…I try to consolidate nodes where I can.…Right now by copying all the nodes in this workspace,…Dynamo runs the same task multiple times.…
