As we saw when adding rooms, rooms require boundaries in order to give us square footage and perimeter information. Without the boundaries the room we will report is unbounded. Many elements in Revit can be Room Bounding by default. This includes walls and floors and ceilings and columns. However, where appropriate, and if our design calls for it, we can actually turn off the Room Bounding feature in certain circumstances. So in this movie, I'd like to discuss the Room Bounding feature in a little bit more detail, and show you a few scenarios where you might want to manage which objects are room bounding.
To get us started, I'm here in a file called Room Bounding, and I am in a level 1 floor plan. And I am going to zoom over on Bedroom Five, and let's highlight and select the room. Now remember, you just use a little X there in the middle to help you find the room. Now notice when it highlights it is wrapping around the closet space over in the right-hand side. If you look at the Properties palette, under Dimensions, you'll see that this is currently 150 square feet. Let's say that I don't want a separate room for the closet, that I just want to assume that the bedroom also includes the area of the closet.
It's pretty easy to achieve. All I have to do is select the two walls--and I'll use my Ctrl key to do that. Once I have the two walls selected, I come over here to the Properties palette, scroll down, and locate the Room Bounding feature. I just uncheck the box, apply that, and now if I find my X again and select my room, you'll now see that the room flows right over the closet as if it wasn't even there. You confirm that on the Properties palette, and you can see that the area is now 171.89 square feet, and so it's clearly changed and gotten larger and taken on the full area, including the closet.
Okay, let's look at another example. I am going to zoom back out. Just use z+ p to zoom previous, and then I'll zoom in and over on this area here, the Master Bath. What you want to be careful of with this Room Bounding feature is that you don't inadvertently turn it off in situations where it's not warranted. So let's say that I had this wall and I came over here and I turned off the Room Bounding when I didn't intend to. What will happen is Revit will generate a warning OK. It's trying to alert us. I'm not sure if this is what you want it to do. What it's actually telling me is I now have two rooms that are occupying the same space.
Let me click OK and let me show you. We have our Linen closet, which if I move around here, is a little difficult to find. I'm going to have to use my tab key. There it is right there. And if you click on it, you see that it's flowing out into the master bedroom space, and even into this little shaft space over here. Let's deselect that. And if I move around over here, I also have a master bathroom that does the same thing. And the reason is, because this wall is no longer room bounding, there is no barrier between those two spaces, so you have two identical rooms on top of one another.
We are going to talk about schedules in a later chapter, but this project includes a room schedule, and we can use this to identify what we're seeing here on this floor plan right now, and what the error was telling us. So if we go to the Schedules and Quantities part of the Project browser and double-click the Room Schedule, what you'll see is linen closet 15 is now listed as a Redundant Room. Now I'm going to drop down this Schedule view like so, and I'll resize it a little bit so that I can see the schedule onscreen at the same time as I am seeing the floor plan.
Let's see if we can position this in such a way that allows me to see both together. Here is Linen closet 15, and here is Master Bath number two. As you can see, the only thing that's different about them is where the center point is, but otherwise it's the same room. Now, Revit does alert us that this one is a redundant room, so it wouldn't necessarily get added to a total of square footage if we were totaling that up. But just the same, you probably wouldn't want to have two rooms on top of one another in the same spot.
Now if I just simply come over here and say OK, let's just delete it then, I am going to do that here in the drawing, and that will generate yet another error. It will say that the room is deleted from the model, but it still remains in the project. Now if I click over here on the Schedule view, you can see that 15 Linen closet is still here; the difference is now instead of same redundant room, it says not placed. So it's actually possible to have rooms in your project file's database that haven't yet been placed in the model.
That's kind of interesting. OK, so let's see how you might use that. Where that's typically used is if you want to come in and build a collection of rooms first before you actually place them in the project. So for example, if I had some walls over here, let's just say I had a little room over here and another one over here, like so, the idea of this concept is, over here on the schedule, I could add a new row. That gives me room number 17, and I am going to just call this Test Room so that we can see it. And you could see I currently have two rooms that are not placed right now.
Now I am going to come over here in my floor plan, zoom in on this area here, go to my Room button. There is a Room dropdown right here. When I click that dropdown you'll see that the two not-placed rooms are listed there: Linen 15, Test Room 17. It doesn't include the rooms that are already placed, because you can't place a room twice. So I could say, all right, let's put Linen right there, and let's put Test Room right there. If I go back to the schedule, the square footage of both of those rooms fills in, because they're now placed.
So this is kind of a somewhat complex relationship between the rooms in your model and how they're placed in the actual space and so forth, but think of it this way. Your rooms are actually containers that hold data. That's really the main purpose of a room object in Revit. So we can build those containers ahead of time on the schedule, populate them with data, give them names, give them numbers, give them comments over here in the Schedule, and then when we are ready we can place them in the room. And usually we wouldn't be ready until we've had actually laid out the wall geometry.
So it's really kind of a sequence thing, or it's an idea about just the way that you want to work, but just know that you can create your list of rooms early and then place them in the project as necessary, or you can wait until you've laid out your floor plan pretty completely and then come in and add the rooms. The choice is really up to you. Both methods are perfectly appropriate, but hopefully in working through this movie and understanding a little bit about room bounding and understanding a little bit about room placement, you now know how to make sense of some of those error messages that might otherwise occur.
