Join Paul F. Aubin for an in-depth discussion in this video Understanding room bounding elements, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] As we saw when adding rooms in previous movies rooms require boundaries in order to give us square footage and perimeter information. Without the boundaries the room would report as unbounded. Now, many elements of Revit can be room bounding by default. This includes walls, floors, ceilings, and even columns. However and when appropriate and if our design calls for it, we can actually turn off the Room Bounding feature in certain circumstances. We also have room separators that we've seen in previous movies that can stand in for room-bounding elements in those situations where we don't actually have any geometry to separate the two rooms.
So in this movie, I'd like to discuss the Room Bounding feature in a little bit more detail, and look at some scenarios when we might want to manage which objects are room bounding and which ones are not. So I have a really simple plan here and I'm gonna zoom in on this Bedroom in the lower lefthand corner, and move my mouse around. We saw that you can find that little 'x' there in the middle and select the room. Now if you look over at the Property's palette, you can see that this is room is currently about 150 square feet. Now, notice that adjacent to it is a closet and currently that closet does not have a room.
So what if we decided that we wanted the area of the room to also include the area of the closet. All you have to do is select this wall and hold your control key down and this wall and then come over to the Property's palette for those two walls and notice there's a Room Bounding feature. All you have to do is uncheck it, and when you apply that and go back and select the original room, notice it is now flowed right into the space that contains the closet, and if we look at the square footage, it's now approximately 172 square feet.
So in a situation like this, that can be an appropriate way to manage the room-bounding element. Now, let me move over to this Master Bathroom area here. And we have this small shaft in the corner. Now, perhaps I want to include that shaft space in the square footage of the Master Bath. I need to be careful here, because when I select this wall, and I turn off the room bounding, I'm gonna get a warning message. And the reason for that is, Revit's gonna tell me that I have multiple rooms in the same enclosed region. So I'm gonna click OK and dismiss that warning, and if I move my mouse around, and try and find the rooms in question, here is the Master Bathroom and then somewhere down here I'll have to use my tab key, but I can find the Linen Closet and you can see that both of them are exactly the same shape.
Now, in a future movie, we're gonna look at schedules in a lot more detail, but what I want to do here is I'm going to Restore Down my floor plan so that it is not maximized and I'll just resize that like so so that we can see that Master Bathroom area. And then over here on the Property's palette, I'm gonna open up this room schedule that I've created and placed in the exercise file. And I want to be able to see the Master Bathroom in the background as I interact with the schedule.
Now, here is the Master Bath and you can see that when I select the entry in the schedule, it highlights on the screen. And there is a square footage listed for the Master Bath at 49 square feet. However, when I go to the Linen Closet, it also highlights on-screen, but notice that in the area column it says redundant room. So this is what the warning message was telling us is that we actually have two rooms in the same enclosed space. Now, you might be tempted to just say okay, well, I'll just get rid of that room then so I'm gonna press the Delete key here in the floor plan and that'll generate yet another warning, and it's telling us that we've deleted the room from all model views.
However, it still exists in the project. And if you look over here at the schedule, it'll say that the Linen Closet is now not placed. So what does that mean exactly? Well, there's a really interesting behavior that we can do with rooms. Rooms are special objects. We've kinda already seen this, and what I'm gonna do is pan over here to an empty space and I'm gonna draw a small, little enclosed area, and then I'll sorta just enclose that into two small areas.
I'm gonna cancel out of there, and then I'm gonna go back to the schedule, and what we can do with the schedule is you can actually on the Rows panel here, click this button to insert a Data Row. When I do that, I'm gonna get Room 17, and I'm gonna rename that from its default room to Test Room, and then over here in the Comments field, I'll type in... "This is only a test." Now, notice that that one also shows up as not placed.
So what I'm doing here is demonstrating a feature of rooms that you can take advantage of if you want to. Let's say you went to the client and got a program of rooms that were required for your design. You can come into your Revit project and using the Insert Data Row, you can create a bunch of rooms in the schedule. You can name them, you can number them, and you can put in other information. In this case, I'm using comments, but honestly you could add other columns here as well and add occupancy information or finish information. Whatever you want.
When it comes time to place these rooms, here's the experience you'll have. I'll go to Architecture, and I'll click on the Room command. I'm gonna accept the normal defaults, but instead of clicking and placing a new room, notice on the Options bar the room says New. That's the default behaviour. It's gonna create a brand new room, which would add to the list. What I'm gonna do instead is click this small dropdown, and notice that the two rooms that are not placed are listed here. So I could take my Linen Closet and I could place it right there, and I could take my Test Room and I could place it right there.
And when you do, let me cancel out of there, I'll select Test Room. Notice that Test Room came in not only with its number and its name intact, but its comments as well. So this is what I mean when I say if you wanted to fill in any of this other information ahead of time, you could, and then all of that information will be there when you finally place the room. I have one more situation I want to point out to you here. Room 16 is listed as not enclosed. So let me go back to the floor plan here, and let's find Room 16.
It's actually sitting right here in this exterior patio. So if all I cared about is having the name and numbers show up in a tag, I can leave it alone. I don't have to enclose the room, but as we saw in a previous movie, if you want to you can enclose this using room separators. Now, in this case, there's no walls out here on an exterior patio so a room separator is the way to go. And notice that when I trace over this patio shape, like so, cancel out of the command, look back on the schedule, the patio now has a square footage and it's properly enclosed.
So room bounding comes in a few different varieties here. Elements like walls and columns and floors are automatically room bounding, but in cases where you don't have a room bounding, we can use a room-bounding edge. In cases where you want a room-bounding object that's already room bounding not to be, we can toggle off the Room Bounding feature and this gives us more control over what spaces our rooms actually represent.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
