direction of the decking

[redwood]

I created the decks with straight deck railing.

I have 2 levels of decks. Both have exactly the same specification in the DBX. The lower one has the railing, as specified, the upper has no railing.

Both Decks are framed and planked correctly, but only the lower deck with the railing has the room title of Deck. I am unable to select the upper deck, as a whole. I don't see any gaps in the corners, so it seems to be all connected. It did have a railing initially. I was having problems with the lower deck, trying to connect the 2 levels with stairs. The stairs kept passing through the deck, to the ground.

One other thing, that may be related. When I do a Full View, in perspective or Orthographic, my model is very very small. This occurs even when I select "Fill window Building only". I'm assuming that this means that there is a object floating, out there in space, that I can't see. This does not occur in plan view.

Any ideas!

Thanks
