Join Paul F. Aubin for an in-depth discussion in this video Adding rooms, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie we're going to talk about the room element. Now a room is something that's pretty well understood without too much explanation. I mean after all, we occupy rooms in our everyday lives, but what is a room really? Is it the four walls that surround the room, or is it the space thus enclosed? And this is precisely the challenge that the Revit programmers had to solve when devising the room element. So in Revit, when we have a room, the elements are special objects that automatically conform to the shape of surrounding geometry, and thus, accurately represent that space so enclosed. However, they don't actually display anything on-screen unless they're selected, which is also the way that we would typically want them to behave.
So let's go ahead and get started adding some rooms. On the Architecture tab, there's a Room and Area panel here and I'll click the Room button or type RM, which is the shortcut. Now the default behavior of the Room Object is that is also creates a tag. So if you look here on the Modify tab, the Tag on Placement button is already selected. It's kind of lit up in this blue color. That's a really handy feature, so we're going to leave that selected. So what that means is when I move my mouse into the model canvas, you're going to see this blue outline, that's the room, but you're also going to see the Room Tag kind of right where my cursor is.
Now, if I place the room out here in empty space, it'll generate a warning and tell me that the room is not properly enclosed. Now, you can do this, Revit doesn't prevent you, it's just sort of warning you. But if I click the Modify tool and cancel out of the command and then just click anywhere to dismiss that warning, that room is actually still there, you just can't see it. So if I move my mouse nearby where I placed it, notice that it does highlight and if I click to select it, there is a room there. The trouble is, when you look over at the Properties, it's exactly what it told us, it's not enclosed.
So it can't calculate any of the information about the room, or really do anything super valuable with it. So what I'm going to do is press Control Z to undo that room, I'll go back to the Room command and start again. And this time I'm going to move my mouse into the floor plan area, and notice that when it's within an enclosed space like this bedroom in the upper left-hand corner, it will flow into that available space and create the shape of the room. So I'm going to go ahead and click to place that first room there.
Now that becomes room number one, and if I place the next one it'll be room two and room three. Notice the tags try and line up with one another. I'm not too concerned about the numbering right now. We're going to deal with that in a future movie, so for right now what I'm going to do is just sort of move around and place a room in each of the enclosed spaces. So the two toilet rooms, the different closets here, here and the utility space. Now if I try and place a room here, you're going to see it flows into all the remaining space because this is just one big open space.
So that's really not desirable, that's not the room that I'm after. So let me go ahead and click my Modify tool and cancel out of there. Now I certainly could draw additional walls to enclose those spaces, but I don't want to change my architecture to accommodate the Room Objects. So what we're going to do instead is right below the Room button there is the Room Separator. And the Room Separator is simply a kind of model line that separates rooms from one another. So you can draw these model lines in any of the standard shapes, I'm just going to stick with the default straight line.
And I'll snap to a point and another point, and then I'll keep going down to here, and then I'll draw one across this opening here, and another one to close off this little foyer. So what I've done is sort of made this an enclosed space, that'll be our living room, our dining room, a hallway, the kitchen and this little foyer space here. So now if I go back to the Room Object, I can easily place the remaining rooms, and notice that they will conform to the shapes of these new spaces that I've defined.
And let's cancel out of there. Alright, so now that we have rooms in all of the spaces, let's look at some of the properties of these rooms. The first thing is, how do you select a room? Well, if you move your mouse over by the edge, you could certainly use your Tab key, and eventually, it would highlight the edge of the room and you could click to select it. When a room is selected, it highlights in blue and you can see it quite boldly, and if you look over at the Properties palette, it will tell you you've got a room selected and you'll be able to read all the properties of that room.
Now there's actually a much faster way to select the rooms than to use the Tab key. So if I just sort of click anywhere to deselect that, and then kind of move my mouse into the space here, I'm going to move in a circle around this tag. And notice that as I move in a circle there, the corners around that tag, you're going to see this X highlight. And that X running through the room is what they call the Room Reference, and all you have to do is click anywhere on that X and that will select the room. So Revit's made it very easy for us to select the rooms, and with a little bit of practice, you'll start to remember where those X's are, and it will be real easy for you to kind of move from space to space and click on the various rooms.
When you have a room selected, over on the Properties Palette, you'll be able to scroll through and see useful information about this room including things like its area and its perimeter, which is obviously very nice information to have. In addition to that, you're going to see other properties about the rooms, many of which are going to be blank, but that you could fill in if you wanted to. So for example if I select this room right here, this is supposed to be my living room. Well notice here that it says it's room number 11, and the name is just simply Room. In fact all of my rooms just defaulted to the name Room.
So I want to change that. And I'll type in Living Room. When I apply that, notice that the tag will update immediately. Tags in Revit are linked to their Host Model Object. So in this case, the tag here is actually linked to this host room. Now having said that, it's actually possible to use the tag as a way to edit the data in the room. So if I select the tag, first let's be clear, when the tag is selected, look at the Properties Palette, notice it says Room Tag, and you don't see all of the other properties that we saw previously.
So the room and the tag are two different things. In fact, if you deleted the tag, it does not delete the room. The room is still here and you'll get a warning from Revit letting you know that deleting the tag did not delete the room. If the tag is not there, the room still exists and I could come down here, select the name, change the name... Change it to a Kitchen. I don't see anything on-screen to indicate that it's the kitchen. If I go back to Architecture, click on the Room Tag button, RT is the shortcut, notice that the tag sees the information of whatever room is underneath it.
In this one if I clicked it would place a second tag for the living room, but when I come over here to the kitchen, it knows that that's the kitchen and I'll click to place it, and now that tag replaces the one that I deleted. So when we first place the rooms, we did Tag on Placement simply because it was convenient. But it's important to understand that the tag and the room are two separate things. But having said that, you can actually use the Room Tag to help you modify the data in the room. So if I click the Room Tag, the information in the tag will turn bold, and I'll be able to edit it much like we were able to edit temporary dimensions when you select a wall.
So you may recall that if you select a wall, dimensions will appear and then you can edit the values of those dimensions and it will move the wall. Well in this case, I can edit the value of the room name... And when I press Enter, it will actually update the information within that room. So if I select the room and scroll down notice that it's now the Utility Room. Now that's true of both values in the tag. So if you change the number, that would also affect the value in the room, so if I select the room, scroll down, you can see its number is now 100.
I'm going to zoom back out. Using either method, go through and name all of your rooms and incidently, for rooms that have the same name, you can select one, hold the Control key, select the other, and then we can change them both at the same time and that's usually a little bit quicker. So the same would be true for these two bathrooms in here, just have to find where that little X is. And then this little X, and then I could change both of those.
And then you can continue like that naming the rest of the rooms. So when you're done naming the rooms it might look something like this. So adding rooms to your model is a useful thing to do to give us an object that represents each of the enclosed occupied spaces within our building model. Those occupied spaces then are characterized by these rooms which will keep track of things like the area and the perimeter and of course the name and number. So it's a really handy tool that we have to help us do things like Room Finish Schedules and Room Lists and just calculating overall program requirements.
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.
